How is a newcomer to this language supposed to 'know' these things? Not to sound like a whiner but I *really* want to use this language I'm just having trouble convincing myself to use it for any projects due to the lack of thorough docs and the 'black box' nature of it.. Instead I'm having to look into something like Ruby (or Python) for my clients project I use python and rebol about equally. For instance, I have a client who wants a language that can be interlinked with apache, so there is no 'mod rebol' but there is a 'mod python', so I use python... but holy smokes! Rebol is **so** much more streamlined than python. Rebol's help feature is very helpful and in my opinion, better conceived than pythons. At least when you use help in rebol for a non-existing word, you get alternative choices, as opposed to python's choice to throw and exception. Having said that rebol 'help is better conceived, it still has a way to go in implementation. Give rebol a try. The differences between rebol and python is the difference between a sportscar and a long-haul truck.

[REBOL] Re: localized func alternative...
* Maxim Olivier-Adlhoch [EMAIL PROTECTED] [040227 14:05]:
Hi all,
Has anyone programed an alternative to func (function, has, does) which declares
every set-word as local by default?
I find rebol's liberal use of global namespace to be the most limiting factor in
scaling rebol to large tools.
No kidding. There much be a reason, but I dunno why.
I'd rather have to define global words than local words (especially in api tools).

[REBOL] Re: oss revisited (real world examples)
Tom: My wishful thinking forces me to bring up what may be a dead horse issue, so I apologise in advance. What's up with rebol and open source these days? Rsharp seems stalled. * [EMAIL PROTECTED] [EMAIL PROTECTED] [040209 08:54]: Just a few comments to throw into a general discussion. Good writing here Sunanda! Open source is not the only model for software distribution. It is a very trendy one And sometimes, it seems, more trendy than useful. ... A potential open-source product will sit somewhere between those two extremes. Depending where we each draw the line, you and I may disagree about the open-sourcedness of a few products that straddle our personal lines. A concept that I have had for some time and is really influenced by a interview I once heard with Carl S: Open architecture (as distinguished from open source): A rebol distributed with binaries that could be linked by either a POSIX- or ANSI-compliant C compiler and has the necessary hooks for 'plug-ins': Real world example: A large programming shop that I know of has literally hundreds of small apps running. These apps are either perl or rebol, depending on whether REGEX features are needed. Since regex components are available via open source, if a regex 'engine' could be 'plugged in' to rebol and a human-readable regex interface written, most of the perl programs would be replaced by rebol. Now, think Rebol for Applications: CAD-related. Enabling rebol to run inside of a CAD system, (as AutoLisp does now), would thrill me to death. Rebol is *so* much nicer to work with than AutoLisp. (for my taste, that is) And, as an alternative to VBA: Enabling rebol to run 'inside of' Open Office as VBA runs 'inside of' Microsoft Office. All of these scenario are very attractive to me and to many of those that I collaborate and communicate with This is both a trust model and a meritocracy -- you've got to earn your rights to be a committer (able to check code in). Non-committers can only suggest changes (or spin off their own code tree and run the risk of it becoming unintegratable with the main tree). I guess that Carl is extremely picky about what code gets checked in to the REBOL code base, and even if REBOL were open source, there'd be precious few people with the right to do that to the official tree. Honest to goodness, I mean no irony here, but that might be one method to overcome the binary skip bug, (as an example) which by Carl's admission (if I read him correctly) has been so hard to fix.

[REBOL] Re: Zope comments (MU)
I'm very interested in zope, because much of my work comes from web programming and about half of the work that I do, I do in python. The other half is done with rebol. I have found rebol much more productive codewise than python. On the other hand, python has many more external resources, and has internal (built-in) features that more easily (as I see it) promote scalability. As a python user, zope has great appeal to me. I don't know enough about it to know how it integrates with perl-sourced assets, and that is an issue with me because my partner is exclusively a perl programmer. As a rebol user, what I have done thus far is develop a system that I call 'MU. 'MU exploits Andrew's 'ML and DocKimbel's 'mysql-protocol, as well as my own CGI resources. The concept is that web content, database acccess and data posting is controlled in a large part by data structures. And it provides and lot of validity checking. Data Drives It (from the Designer's Tip Sheet). I'll be (alpha . beta)-testing this over the next couple of months as I develop another web site and will then release it with all dependencies to public domain. The next step for me would be to add more zope-like features, like content and project management. I would hope that when I do go 'public' with it, that there will be enough interest to generate constructive criticism, lord knows I need that. In the meantime, if anyone can offer any ideas on how I can handle project and content management 'zope-like' and also how to integrate with perl applications, contact me OTL. One of the strategies for perl integration would be a language-independant way to create associative lists from delimited text files. :-) There's a way to resolve some interoperability issues. Yeah, zope rocks and imitation is the best form of flattery. tim * Jason Cunliffe [EMAIL PROTECTED] [040113 10:18]: From: Petr Krenzelok [EMAIL PROTECTED] It is just two weeks one of my friends visited me to help me to install Fedora server. He brought two books with him - Cocoon and Zope. Zope seems to be interesting, he showed me how he used some module for digital photo catalogue. Nice, but really nothing what could not be done in IOS in a MUCH clearer way, at least to me. He admitted, that Zope is nice even for beginners, but once you decide to modify some unsupported functionality, you have to go deep python. Zope is very easy to use for fast turn-key installation. Amazing what's in there. Be warned, all the books on Zope are already out of date, though do give some helpful overview. Zope development moves pretty fast. When we were developing with it four years ago we found the simplest was simply to bypass the complex Zope framework and develop external python scripts for Zope. Basically just single nice readable Python script with a few critical calls into the Zope architecture. Worked beautifully, thanks to the fact that Zope invites many ways of working. There are many Zope products - plugin extensions, but they are almost all individual experiments which people have generously shared. Most of the time people just them as-is or adapt in small ways. The result can be quite a spaghetti of versions and documentation to sort through. The most popular ones are far better documented with plenty examples and people who can help. One of the best kept secrets about Zope is Jerome Alet's ZShell http://www.librelogiciel.com/software/ ZShell : Manipulate the Zope Object DataBase with Unix shell like commands Fascinating , with ZShell, instead of the struggling manually with boring gui interface, or the deep syntax of Zope OO namespace, how it suddenly can become so simple to program Zope. Jerome developed this very familiar concise little tool to sit on top of this enormous framework with nasty syntax. In the process effectively changed the paradigm by combingin old and new in an obvious way, but which had not been obvious to others :-) Also interesting to note that one of Zope's most enticing and clever paradigm -- 'acquisition' -- has proved to be difficult to work with. Ironic because it's the innovative Zope features everyone falls in love with. But it can be brain-twister in practice. 'Acquisition' provides a url-like path syntax where objects inherit methods and properties by searching up the tree of their parents till they find the first match. Then apply that. Its a brilliant idea. But after years of work, I believe the new Zope3 now being written is to fresh code and component-based architecture. I am not surprised they changed, but always believed Acquisition was such a different paradigm that it really needed a different kind of interface to manage it. And that never happened. An interactive map for example. But core Zope developers seem to be non-visual creatures. Reblets seem to be really better aproach to me.

I looked at the function dictionary on the REBOL web site and did NOT see a reference to emailer. Perhaps the dictionary has only /core functions? Emailer is not available in /core This makes me wonder what other functions there might be that are not documented. Does everyone else just stumble across these things or is there some documentation I am missing? One would think that the REBOL Function Dictionary would contain all the functions. Unfortunately, rebol documentation has a ways to go yet. :-( I only use rebol/core for projects, but when I fire up REBOL/View 1.2.1.4.2 21 and invoke help emailer, I get pretty good documentation on the function. Since it is a mezzanine function, you can also look at the source code for it by invoking source emailer I know I can list all the system words and just look them over one at a time to see what they do. Is that what it takes? Sometimes, yes. Is the missing emailer function just a single omission that slipped through the cracks? Unfortunately, I think the answer is no.

'x == false print 'x x print x ** Script Error: x has no value ** Near: print x Think of a rebol word as a white-space delimited string. a rebol word may or may not have a value. But it always has a spelling. If you've done anything with LISP or scheme, this is the inspiration for rebol Testing for a value requires a single quote as in value? 'x as opposed to value? x Using 'attempt is guaranteed to return a 'none if the word has not value. There is a tutorial on rebol evaluation techniques using my 'fetch function (somewhere) you might want to dig into that some time.

* Ashley Trüter [EMAIL PROTECTED] [040102 21:46]: Hi Tim, But I believe that lists and blocks are implemented differently internally, but I'm ignorant as to how. any comments on this? Hi Ashley: Conceptually, a block is just a collection of values where the sequence is directly known (ie. like an array REBOL knows where the Nth value is). A list on the other hand ensures that each value knows where the previous and next values are (finding the Nth value in this case involves walking the list one value at a time). That much I'm aware of. What I didn't know is if blocks are single or multiple dereferences, and if lists are single or double-linked lists. Your *very nice* test results gives some clues My guess is that the lists are double linked, and the block items are dereferenced just once. (resizable arrays?) My thought had been that perhaps using a list instead of a block for mysql-protocol in converting data types might be more efficient, however, from your test results, it's apparent that would not be the case. Whereas 'insert entails resizing the entire block and reallocating memory, big overhead. Nice work! Thanks. We should archive this somewhere. I sure will. :-) regards tim The following test attempts to highlight the strength and weakness of each series! type (keep in mind that the memory cost of list! / hash! is higher than block!).

* Defiant Mail [EMAIL PROTECTED] [040103 15:42]: I was wondering why a mail list instead of a forum? It would make things so much easier just to enter a search than to read through hundreds of archived mail's for a quick answer, furthermore it can send e-mails notifying users of new posts just like a mail list. We have several servers and I imagine others on this list also have the space to host a forum and icon board and phpbb take about 20 seconds to setup, so I ask again why no forum? The only forum I have found is in french and it has no language selection for non french users. Any ideas why there are no forums for rebol users? Thank's for your time sorry if that sounded like a rant... -Mj. There's no disputing taste I guess, but I can roar through my email using Mutt, and prefer it that way, but there's nothing wrong with options -- back in the early days of CGI, I use to build forums for customers A forum is more of a community, better organized and answers for newbs like myself are readily available. Yes, I would think a forum does 'model' a community well. In either case it is important not to 'overload' a thread, but to create a new one or a new subject as the content changes - IMHO - question: can a forum such as you describe above 'mirror' a ML? Also, isn't forum access speed controlled by bandwidth - since it is web-based? I do a lot of reseach with newsgroups and slrn/slrnpull which makes it exceeding quick to navigate among subject threads, also very nice. cheers tim -- Tim Johnson [EMAIL PROTECTED] http://www.alaska-internet-solutions.com -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

Here's a different approach:

context [
a: b: 2
set 'public-fn func [][print [a]]

At this time, 'public-fn is still 'public'

Very good point. In my non-parse function, I wrap the function in an anonymous object, intiallize an 'alloc word to a value of 128, and make algorithmic adjustments to that size based on the length of the return value. (which is a string) ;;;it starts a string and ends a string why a block in the middle? ;;; pre-allocating the correct length is golden ;;; and this result can't get any longer blk: make string! add length? str length? to string! subs Also, it is arguably not good programming practice to use the 'circular approach to the 'subs. After all, I've been programming with fixed replacement lists in C and python for years and even GCC gets grumpy about tokens and replacement lists being of a different length. And since rebol will cheerfully insert a none as a string subset, then I might end up error trapping any overruns and dumping the 'circular approach. That would eliminate the 'guessing' parse/all str[ some [ copy txt any non-delims ( ;;; use 'any in place of 'some because what if str had ;;; ...%s%s... ?

* Konstantin Knizhnik [EMAIL PROTECTED] [031217 07:26]: Rebol has awful implementation of hash tables. First of all, it is very inconvenient that there are normal set/get operations. You have to use something like this: h: find/tail hash key either h [change h key value] [append append hash key value] instead of hash[key] = value Grrr! I *hate* doing that, and in python I have to do it a lot! In rebol, I just do hash/que 'val key much nicer, it took me half a day to implement my own object, but it was well worth it. in most other high-level languages. And as far as Rebol hash is also series, appending element to it cause Hmm! Are you not using to-hash ? a lot of reallocations, so complexity of insert operation seems to be linear (instead of constant). And if we use insert hash instead of append hash (not insert tail hash), then performance becomes really awful - copying all series element increase complexity to quadratic and insertion of 10 integer elements in hash takes about half an hour (less then second in all other languages). I haven't run tests like that, but see my comment above. And as far as object cache is one of the main components of object oriented database, such inefficient implementation of hash table leads to poor performance of Rebol DyBASE API. All language have their strengths and weaknesses, *and* their best fits. Mysql is a best fit for rebol IMHO, rebol mysql access on our large, multi-language projects beats perl and python hands down both in access speed and in impelementation/coding. One of Rebol's strengths is TCP/IP is native (compiled into the binray) and the mysql-protocol exploits that splendidly. On the other hand, perhaps the native 'hash' of rebol is not is advanced as the btree approach that python uses. I do believe that a true hash datatype is a linked list, though. still, it is nice to see these tests and the work that you've done. regards tim C regards C Cyphre C - Original Message - C From: Konstantin Knizhnik [EMAIL PROTECTED] C To: [EMAIL PROTECTED] C Sent: Wednesday, December 17, 2003 12:15 PM C Subject: [REBOL] Rebol API to DyBASE Hello all, First version of Rebol API to my object-oriented database DyBASE is ready.

I can think of several ways to write the rot13 conversion in a much more natural-to-REBOL style. The quickest (for me) to write uses REBOL's object mechanism, and generates the translation table algorithmically at object set-up time (as a one-shot initialization to reduce risk of typos): rot13: make object! [ xlate: make string! 78 for ch #a #m 1 [append xlate reduce [ch ch + 13 ch]] for ch #A #M 1 [append xlate reduce [ch ch + 13 ch]] code: func [s [string!] /local result] [ result: make string! length? s foreach ch s [ insert tail result any [select/case xlate ch ch] ] result ] ] It would be invoked on a string by evaluating rot13/code somestringexpression and extending this to process an file (or standard input) is easy.

Well, I did it again, and punished myself severely for the transgression, but I can't bring back the time I lost I created a subroutine in a context and called it 'reduce. And I forgot to either redefine or provide an absolute path for system/words/reduce. Bad Tim, bad, bad Tim! This poses the need for a wonderful one-liner that would throw an error or warning in case a word is defined and used in a context that already exists in system/words. I'm just starting to dig into lisp as a part of learning emacs and I believe that language does have such safeguards, but I haven't been able to get to that understanding yet. Any ideas? comments?

[REBOL] No return Value???
Hello Rebols:
I've got a question:
I've written a function called 'fetch, which has print
stubs to help follow the flow control.
If you evaluate 'print with 'fetch, no value is
returned.
Can someone tell me why this is so?

Example:
do %test-fetch.r

fetch 'abc

follows:

print does not return any value,
Yeah, I know, I will probable have to use a tmp word,
test it and use a default return value.
I had to work around that in encompass... (hence the /silent refinement)
you can build up a function which returns no value:
a: func [data][
; do what you want with data
return unset 'data
]
the above is not really usefull but if you want to free the memory used up by data
(cause each word in a function keeps its value in between each function call), then
this is one way of ensuring it does not hang around.
ladislav and gabrielle might correct me if I'm wrong.

G Some irony here. Read on. * Maxim Olivier-Adlhoch [EMAIL PROTECTED] [031128 11:41]: sighArguing over editors is *such* a waste of time. There's no disputing taste. Not arguing... questioning, wondering why the 'powers that be' use it ;-) If I'm going to waste (read as curse ;-) tens of hours to be as efficient as I am in other editors I use, I have to get a hint of why I'd want to agravate myself on the short term. :-) I have used vi in the past and altough tell me its superior, I've yet to see anyone actually using it properly, even after a while. I use vim extensively and love it. And I've barely touched the surface of it. The paradigm of modal editing (which allows one to use keystrokes as enhancement) *is* an acquired taste and I would not wish vim on anyone who didn't choose to learn it voluntarily. Some people like point-and-click, others prefer the keyboard, it's wonderful to have the option. Without going into the details, it is to my advantage to learn (x)emacs as well. I feel that it would be helpful for those who have particular editors, (whatever they may be...) To share information to help to make whatever editor they have more productive. For those of you using windows (I don't anymore for developement) two I recommend are 1)Boxer 2)Elan's Editor. In fact, regardless of the platform, it is worth investigating (in my opinion), how to use rebol to make rebol editing easier. thanks for all answers, even those that are yet to come.

[REBOL] Re: No return Value???
* Elan [EMAIL PROTECTED] [031128 13:42]:
Hi Tim.
1. You can use unset? to check for words that do not return values .
unset? print
Thanks for reminding me.
== true
if unset? print [result: unset]
2. If you need to assign the return value of the tested function to some
local word, you can use set/any to avoid an error.
3. Why doesn't print return a value? Wel;l, I suspect that is because
the purpose of print is to display its argument. If print were to return
a value, it would not only be displaying its argument, it would force
the REBOL interpreter to display print's return value as well. I.e. you
would see a combination of the printed argument and print's return value
on the screen. Instead of
print
which is the expected result, for instance, you would get
print_with_return: func [arg] [ print arg return true ]
print_with_return
== true
BUT the argument to print was NOT ==true it was .
Hope this helps.

I program about equally in python and rebol python may have more users, but its also a wild jungle. its also found it fun to follow a thread called: Re: Too much builtins (was Re: Python's simplicity philosophy) when I know that it takes 50 modules to do what rebol does with the amount of code in the equivalent of 3 of them (without needing to actually load them ... ;-) I am glad that the python community is addressing this issue - I just spent the better part of two days trying to resolve a pyGTK interface, Yikes! what a can of worms This while running 5-10 times faster... and having a much more reusable code base in any circumstance. I've really not seen such an all-around speedup of rebol over python to that degree. What comparisons have you made? I would feel safe suggesting that line-for-line, (speaking from my experience only) rebol is probably 50% more productive than python. Python appears to take cues from other languages with their adaptation of list comprehensions. It would be nice if they could blur or eliminate distinctions between assignment and code like rebol does. They still have nice souls on the list, I got an answer within the day like here. Both MLs are very helpful, yes I have found that too... But when reading about the more philosophical debates, like we sometimes have, there seems to less intent on cooperation and solutions than on proving someone's point. I do find more opinionated positions on the python ML, but then 1)python is more 'established' than rebol. (older 'community) 2)Python implements a more 'conservative' or 'structured' or 'disciplined' (pick your adjective here) approach than rebol. no need to follow up, it was just a short message to illustrate how this list fares towards its competition :-) I tend to make the opinion here from time to time that rebol needs to build up a distribution package like python and perl have. That would attract more programmers to it (IMHO), and that would include my partner who is a dedicated 'perlhead' mostly because of all the modules. On the other hand, care must be taken to insure that 'resources' don't become too dependendant-heavy, which probably lead to the python thread that you're referring to above.

For those new to rebol(and for you gurus to critique if you so wish),
I'm including a subroutine that I use frequently.
One of rebol's distinctive features is the variety of ways
in which code can be evaluated. Coming from architectural
languages like ASM and C, and using more conventional scripting
languages like python, I had a hard time getting that
under my belt. Still working at it actually.
and the fact remains, rebol documentation doesn't really hammer

[REBOL] Rebol and vim: (was lost the case ...)

And BTW, I don't believe that RT would have to provide source code. Vim doesn't care about python binary source. ===Rebol as emacs-plugin: http://www.frozen-north-linuxonline.com/Howto/REBOL+Emacs.html http://www.frozen-north-linuxonline.com/Howto/REBOL+RMAIL.html Hi Volker: Small World! That's an article that my partner and I published, written by Sterling Newton. :-). I guess vim can work similar. Sorry, I don't believe I made myself clear there. What Sterling writes about in that article is using 'plugins' *for* rebol. I'm talking about using rebol *as* a plugin. I have extensive plugins *for* rebol in vim, as do many others on this list. Those plugins are written in either native vim script or imbedded python. read on: Your emacs code below is elisp script, and the elisp interpreter is imbedded 'inside' of emacs. Vim has the 'hooks' to actually compile the following interpreters: ruby, python, perl,tcl (at least) into the vim executable - just as elisp is in emacs. Therefore one can write an editor plugin in any language that has it's binary inside of vim, just as you have writen the elisp code below, which is processed by the elisp interpreter, which is imbedded in emacs. This is comparable to the apache 'language modes', which essentially do the same thing for the perl, python, php etc. One of the neat things about Vim (and it's developers), is that it is a very inclusive design that is conceived to closely interact with other systems and applications. (One of the gnu-est of the gnu applications) Wouldn't it be cool if the 'emacs' (actually elisp) code could be written in rebol? I'd love it. For instance, yhere are extensive plugins 'for python' written 'in python' that turn vim into a full-fledge python IDE. BTW: Volker, I'm really interested in learning to program rebol in emacs, perhaps someday I could prevail upon you to share some of your elisp plugins with me. I orginally wanted to learn emacs, but I frequently would ask questions of comp.emacs and often those questions would go unanswered - unlike this ML and the vim ML - which is why I went with vim. For instance, emacs can't distinguish my imbedded keypad, where vim and Xemacs can.. and no one can tell me why or how to fix it. :-( And rebol and lisp are quite similar.

[REBOL] Re: lost the case ...
I'm not going to quote anyone here, because I'm taking a different attack than Pekr did - but it is worthwhile to take the same subject line. Given the context for which I generally use rebol - web programming - it is the most productive programming language that I have ever used. And I know wherefore I speak because I've worked in about a dozen of them. Currently, about half of my income comes from rebol code, about 40% comes from python and another 10% from C. But I am self-employed, own my own business and in most cases, I can deliver product in whatever source I choose. I am also fortunate that my domain hoster hosts rebol. If I were to use python as an example - rebol is more productive *but* python has more resources. *And* is more less propietary - real important concept. The same can be said for perl and that is why my business/programming partner is sticking with perl rather than switching to rebol despite being very impressed with it. I've hammered this time and again on this list, and I will say it again, there is *so* much talent in the rebol community that a real *distro* could be put together that could rival anything that python or perl have to offer. I have no doubt whatsoever that would attract more programmers. On another note: Let's say I have a client who says Tim, I want your code in C. I don't care if it will take more time than rebol. Rebol is obscure. Now, given that scenario, suppose I've got rebol imbedded in my editor (which is VIM), just as python is imbedded in vim. If that were that case, I could program rebol to automate the writing of C. That would make for a remarkable plugin, and I'm sure that the vim developers and the vim community would work with RT to make that happen. that would be just awesome and give rebol that much more exposure. And BTW, I don't believe that RT would have to provide source code. Vim doesn't care about python binary source. Rebol has taken a proprietary path that I am not sure that I agree with. I won't program in view, because TK has so much more application. This isn't an opinion, it is a business decision. And anytime that I need to do stuff with compressed files, I will use python. Why - rip files are proprietory. Not too long ago, I suggested on this list, that rebol might benefit from incorporating the regex engine (which is public domain code), such as perl does. On of my brothers is project engineer for Motorola. He uses rebol and perl extensively in-house. Rebol for TCP/IP stuff, perl for regex. He tells me that if rebol would adopt regex, that his perl programmers would be getting real used to square brackets. That is - they would be using rebol instead. Just my 5centsworth.

As I have not installed any of the X packages, I cannot install any sort of GUI type Web Browser. Although I can use Lynx, the text browser but it is very restrictive. Is it possible to use/build a small Rebol web browser of the most simple form, something to a standard of MS IE ver 3 or 4? Looking through the rebol community there are some excellent products and perhaps this issue has already been developed. I also downloaded Rebol Core View for Linux and plan to use it above the command line linux. Hey Ben. I don't use view that much but I believe it needs 'X' to run. In fact I just tested it from a regular console. (didn't work) Why are you choosing not to install X?. The command line is available from X via any number of xterm consoles, and you can Ctrl-Alt F(n) to a number of 'real' consoles if you want - from X. BTW: This is slightly off-topic, but if you want a small browser, super-fast (but doesn't support frames), try Dillo. It is almost as fast as lynx. I use it for browsing documentation.

Thanks for all of the input. Andrew and I got into an
OTL thread, which I'll soon route back to the list.
FYI: I'm toying with an idea. I have already developed
an object approach with uses data structures to generate
'ML code (Andrew's 'ML dialect). It's still in beta (gamma
really), but promises to cut down on coding and I've
developed a parallel resource in python.
Think Item #4 in the Designers Tip Sheet:

The next step is to create the data structures from
a text file, ultimately to perhaps be produced by
non-programmers, thus a bullet/idiot-proof approach
must be taken.
Will post further when I hear back from Andrew.

append al-block load value
Hmm - I should've looked at the function properly. :) (See my
previous post, which you can disregard due to what I say below about
syntax errors using load.)
With ... load value as Tom suggests above, names such as Tim
Johnson would be converted to two words and not a string, so a check
for spaces and perhaps other characters would be needed to prevent
that. ie, you'd return a string if a space was discovered. Another
problem would be syntax errors when load hits text it can't recognise
as a valid datatype. So, an error check would be needed too, with a
string returned if you did get an error.
I get the feeling though you'd be better to force what datatype they
should be based on the names encounted, (ie, age = decimal,
occupation = string), as the format of your data may not ever be
quite right to always do a correct conversion.

type?/word
otherwise it return a datatype!, which molds the same as the word datatype!,
but it is not. the word number! is set to the value number!, which is
confusing. you can use reduce too.
! mold/all reduce [number! series! money! time! date! char!]
== {[#[datatype! number!] #[datatype! series!] #[datatype! money!] #[datatype!
time!] #[datatype! date!] #[datatype! char!]]}
ing.
type? type? 2
== datatype!
type? type?/word 2
== word!
thanks!

And example of .dbf layout is at http://www.geocities.com/geoff_wass/dBASE/GaryWhite/dBASE/FAQ/qformt.htm Given this information, one *should* be able to parse a .dbf file on a binary port with just rebol/core.

That's because the browser interprets the input tag like this:
input type=text name=testing value=
In other words, the value attribute is an empty string, which is why
the browser doesn't show {boo-boo}.
I understand...
There's also a fault in my ML dialect, as I never considered that people
might want to display text with double quote marks. My ML dialect (or
maybe Build-Tag dialect) should check every string! attribute value and
'escape' any double quote marks inside (so that people don't have to
worry about this.
I would prefer that people didn't use them. Currently what I'm doing
is just eliminating them, however, sooner or later some user is going
to insist on it.

[REBOL] Re: 'ML Article
* Brett Handley [EMAIL PROTECTED] [021012 20:51]: In my opinion 'ML should be part of a rebol standard library, and documentation, examples and articles should be attached to each component of such a standard library. I think the ML is very valuable. Though it could use some reviews before it became part of a rebol standard library. For example, I think that it can be more flexible by not requiring a compose. I suspect there are other additions which could give it more bang for buck too. I think VID is a good reference for the purpose of judging power and flexibility for effort. All that said I think the ML type structures have a good use for expressing a special type of tree and could be used for more than just markup - and at some stage should have a home in a standard library. My concept of a standard library would entail such reviews as you mention above It would make for a better product.

* Carl Read [EMAIL PROTECTED] [020928 13:52]: Well, I was thinking of it being just another script the kids would run on the computers they were using so they could test any CGI they did themselves by looking at it with a browser. I wrote such a script so I can test the CGI I do locally before sticking it on a real server. I just have two REBOL consoles open, one for the server and one for the script I'm working on. Ahh... talking about a simple socket server.. I beg to differ, even eight graders get that one, And I still don't know how old an eight (eighth?) grader would be. This is one area where numbers win out over words in an international forum Tim. (: Sorry: Eighth grade is middle school - the eight of 12 grades and would precede freshmen high school. 13 - 14 years of age or so Girls ain't dumb. (; You're preaching to the converted ... Grace Hopper (Admiral Grace Hopper at that) developed COBOL, and my niece Jessica interned at RT two years ago Besides I married one If you were trying to attract kids to writing as a profession, would you bring in writers of fiction or writers of car manuals or adverts as examples? In other words, would you chose a writer of accounting software over a games programmer to inspire the kids? I'd take what I could get in this limited area and I show them some of my CGI sites built with rebol. We are inviting them to download 'view to play with, and maybe there's some rebol/view scripts online for them to run? For those of you reading this, Carl took part in a mailing list that was set up for this class a year ago. It was terribly dead, Yes - it didn't really get started. It would really need at least two enthusastic posters amongst the students to start the ball rolling I think, but that didn't happen. Yeah, couldn't even get a good argument going we are trying a chat room now, but it will be staffed by the teacher of record and myself only one hour a week sigh and paranoid school sysops aren't letting anyone else in (so far). I'm wondering if the reason you only got an Australian and a New Zealander as the REBOL mentors had anything to do with the less litigious nature of Downunder culture? I can imagine those in the US and probably elsewhere not considering it worth the risk to get involved. Sad. Do kids think lawyers are sexy by any chance? sighWe are going beyond the school district here... I'm disheartened to report that the Human Services profession here is very anti- technology and has turned down many opportunities for tekkies to help them. Example: We have a very high suicide rate among teen-agers here, and when several of us local programmers offered to build software to help crisis line staffers, we got no takers ... just one sad example /sigh -- Tim Johnson [EMAIL PROTECTED] http://www.alaska-internet-solutions.com http://www.johnsons-web.com -- To unsubscribe from this list, please send an email to [EMAIL PROTECTED] with unsubscribe in the subject, without the quotes.
