[REBOL] how to format the result of divide operation
Hello, Can anyone tell me how to format the result of divide operation? Say, 1 / 3 gave me the result 0. what can I do in order to get 0.3 which has only one digit after the point? Thanks for any information. Tiana

[REBOL] empty context possible? Re:
In einer eMail vom 16.02.00 14:05:52 (MEZ) Mitteleuropäische Zeit schreibt [EMAIL PROTECTED]: Is it possible to create an empty context and put only selected words in? for security-reasons, like postscript does. (i lost her mail, so by hand :) Gabrielle answered ([EMAIL PROTECTED]) Yes, it is, but you actually need to create a context with all the words set to UNSET!. You can refer to the message 95706 I posted to this list on 31st January for an example (you can find it on http://www.rebol.org/ or request it to SELMA). I did and got something similar to this, but was able to hack it with going to global scope by "/probe" instead of "probe". so for security this is not enough!! (Gabrielle, please don't try this with "/delete rebol.exe"!!! But thank you for the adding-of-contexts-example! I understand this stuff now much better! :) REBOL[] allowed: make object! [ ; only this two allowed, not "probe" for example.. print: get in system/words 'print none: system/words/none ] all-unsets: use first system/words ['system] code: [print "Hello!"] malicious-code: [/probe "hello"] ; the "/" breaks out! bind code all-unsets bind code in allowed 'self do code bind malicious-code all-unsets bind malicious-code in allowed 'self do malicious-code Gruss Volker

In einer eMail vom 17.02.00 04:39:17 (MEZ) Mitteleuropäische Zeit schreibt [EMAIL PROTECTED]: Those interested in new and unusual programming constructs, take a look at R++ from ATT, where Bjarne Stroustrup, the inventor of C++, works. Here's the link: http://www.research.att.com/sw/tools/r++/ Quote R++ extends the C++ language with a single new programming construct -- the rule. In addition to data-members and member functions, R++ adds a new kind of member to C++ classes namely "member rules". A rule is a statement composed of a condition and an action that specifies what to do when the condition becomes true. Whenever some program data changes, rules whose conditions involve that data are examined, and if a rule's condition evaluates to true, its action is executed. The action may of course modify data and therefore trigger other rules. Currently R++ is implemented as a pre-processor. It translates R++ rules into C++ code. /Quote What would this look like in REBOL?

[REBOL] Parse questions ??
Hello All, I have a file consisting of lines in the following format: "23123+34234+234234-23423+3-" ie, n digits followed by a sign etc etc. The only way i've been able to extract the data into a series is to do two replaces, replacing "+" by "+ " and "-" by "- " and then parsing it using the space as a delimiter. I can't use the sign as a delimiter because that only returns the value and not the sign. My first question is, should parse allow the delimited character to be optionally returned by way of a refinement?? In this case the sign is a delimiter but also an integral part of the data. The other problem i had was once i had the data in the form "123+", i wasn't able to convert it to decimal, because the sign was at the end and not the beginning, so i had to write code to move it. Do people think that decimal and integer should be modified to allow for a optional sign at the end?? Thanks. Mike.

[REBOL] Rebol doesn't return headers under IIS 5, what am I doing wrong?
Hi all, Well, setup REBOL under M$ IIS 5.0 but can't get the scripts to work. I'm testing the cgiform.r script at the moment (you can take a look at http://amiga.student.utwente.nl/cgiform.html ) But I get the error message: "CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:" And that's it, it doesn't seem to do anything (I tried putting in a "send" command, but I don't get any mail). I think REBOL isn't executed. I guess the problem lies within IIS, but I don't know where! Anybody have any idea? I've setup IIS the way Scott told me (and that same way works for PHP3, which I'm also trying my hand at :-) -- Ewald Börger

Hello All,
I have a file consisting of lines in the following format:
"23123+34234+234234-23423+3-"
ie, n digits followed by a sign etc etc.
The only way i've been able to extract the data into a series is to do two
replaces, replacing "+" by "+ " and "-" by "- " and then parsing it using
the space as a delimiter. I can't use the sign as a delimiter because that
only returns the value and not the sign.
My first question is, should parse allow the delimited character to be
optionally returned by way of a refinement?? In this case the sign is a
delimiter but also an integral part of the data.
Hi Mike,
You are using parse in its simplist form, as just a split function,
whenever you need more from it, you can create your own parse rules.
See attached script, and the 'parse topics in the docs
The other problem i had was once i had the data in the form "123+", i
wasn't able to convert it to decimal, because the sign was at the end and
not the beginning, so i had to write code to move it.
Do people think that decimal and integer should be modified to allow for a
optional sign at the end??
I admit I don't see this form very often, so I would not see any need for it
to be built in,
but others may. It only takes one or two lines to convert this format to an
integer, it doesn't
take much to make your own converter. (see attached script)
Cheers,
Allen K
