[REBOL] Multipart emails Re:(2)
I did some work for a multipart/form-data decoder; it needs some work for more generic MIME handling, but if you are interested... Ciao, /Gabriele./ Gabriele, can this decoder handle form-posted data? If yes (or if you think it could, with some changes) can I please have it?

[REBOL] security-requester a risk?
When rebol asks for lowering security, it makes "yes" the default. a occasionaly return gives free way. i think "no" should be the default, at least as an %user.r-option? Volker
[REBOL] communicate with program with stdin/stdout - end markers?
I want to communicate with another program with stdin/stdout. i need a way to detect the end of a message, and i want to use the normal print/input. since a data-string can contain my end-marker, i have to mask it out. Can this protocoll-stuff be used to generate a filter for the normal stdin/stdout to do this? and how? Volker

[REBOL] Money Trouble? Re:(2)
Hi,
I want to present a different point of view. My experiences are,
that the binary representation is as good as the BCD for the
accounting purposes. I do have an accounting program in Rebol
using Decimal! as its basic type.
If you want to be exact, you shall always be careful of what you
are doing and BCD can be no replacement for brains eg in Euro
conversions (three or more decimal digits are needed for
intermediate results) or some average computations.
The BCD is more convenient only in the cases where the operations
don't
yield results with infinite number of decimal places, or results
with more decimal places, than the program should process. For
the more complicated cases it's simply the programmer's task to
take care.
a part of my accounting program:
round: func ["Round a number"
n [number!]
p [integer!] {Decimal places - can be negative}
/local factor r
] [
factor: 10 ** (- p)
n: 0.5 * factor + n
n - either negative? r: n // factor [factor + r] [r]
]
add-m: func [a [number!] b [number!]] [
round a + b 2
]
sub-m: func [a [number!] b [number!]] [
round a - b 2
]
(the above doesn't mean, that I consider the "rounding" of Money!
values in Rebol to be correct)
Just my $0,021
Ladislav
Thanks for defending my cause ! I already posted some messages
on this
subject but I didn't found a so obvious sample to show the error
of using
binary when dealing with money.
I'm lobbying for a decimal internal format for money! values, as
in COBOL:
REBOL and COBOL should have more than three letter in common !

Subject: [REBOL] Money Trouble?
Hi folks,
Over the weekend I was playing with the REBOL money! datatype
and
discovered
some problems. Using the REBOL/Core console:
x: $10
== $10.00
y: x + .01
== $10.01
y - x
== $0.00 ;surprising result, displayed value is
not correctly
rounded
We can check what is happening by retreiving the decimal value
from the
money values:
dx: second x
== 10
dy: second y
== 10.01
dy - dx
== 9.79E-3 ;this is the actual numeric value
of y - x, it
should round to .01
The problem seems to be incorrect or absent rounding of the
difference:
to-money dy - dx
== $0.00
Checking when to-money will return .01 vs .00:
a: to-money "9.99934E-3"
== $0.00
b: to-money "9.99935E-3"
== $0.01
Clearly both of these values should round to $.01.
There some other anomalies also:
(y - x) * 1.01
== $0.00
(y - x) * 1.1
== $0.01
(y - x) * 10;displayed result is wrong by a
factor of
ten
== $0.01
(y - x) * 100 ;displayed result is correct
== $1.00
These problems are not due to the round-off intrinsic to
decimal values.
Even in the worst case we have 15 significant digits of
precision. The
example shows incorrect rounding in the 4th significant digit.
I wonder whether others have noticed this problem?
Note: this has been CC'd to feedback as a bug.
Cheers
Larry
[REBOL] dynamic word names 2
What if I want to append a dynamically created word with a value that
belongs to a word the representation of which must also be dynamically
created in the script?
Assume an earlier script created the following word values:
lineword1: {hello}
lineword2: {good morning}
lineword3: {good day}
Now I want to append them in order to the word "messagebuilder."
The value of "count" is the total number of "lineword" word values with a
numeral appendage.
How can I accomplish what lies within the parenthesis?
for build 1 count 1 [
append messagebuilder (with the value of a dynamically created word)
]
Thanks.
-Ryan
If I understand right, you want to dynamically create words and assign a
(changing) value to them. If you want to append, just replace the "set"
(below) with "append".
foreach line page [
count: count + 1
set to-word rejoin ["linewords" count] line

[REBOL] Some niggley things
Hello, Rebols: #1 files: READ %. gets the current directory, but how do we do it with a set-word? Example: directory: %/partition/drawer/drawer files: READ %directory(how to deal with "."?) doesn't work because (among a few things) it tries to read the current directory. I don't want to use CHANGE-DIR because then REBOL persists to look at that drawer, which is *very* annoying when trying to re-run the program. #2 "files" (above) will, eventually, be a block of about 300 file names. I need to know how to take five file names at a time and make a string that is: "name+name+name+name+name", to add to a URL. I didn't see an example of how to parse a string in this way (take five elements at a time until the end of block), nor did I see how to efficiently make a string using a repeated separator. Do I need to deal with the end of the block or is it automatic? -- ---===///||| Donald Dalley |||\\\===--- The World of AmiBroker Support http://webhome.idirect.com/~ddalley UIN/ICQ#: 65203020
[REBOL] return statement Re:
Hi Phil, 1. As a matter of principle REBOL lets you modify the value of each and every word. There are no keywords. This is good. 2. To protect all words that are part of the REBOL vocabulary use the built-in function protect-system. 3. To protect selected words (here return) use the function protect, as in protect 'return return: none ** Script Error: Word return is protected, cannot modify. ** Where: return: none You can have it your way without limiting REBOL's flexibility. At 10:22 PM 3/7/00 +, you wrote: Consider the following code : REBOL [] ; Check function check1: function [] [] [ x: "A" if x none [return "Error"] print "This should not print" return none ] print check1 does not print the text (correctly). However adding the line return: "Error" gives REBOL [] ; Check function check1: function [] [] [ return: none x: "A" if x none [return "Error"] print "This should not print" return none ] print check1 does print the text (I accidentally added this line to a sub-function, instead of return none, and it took me ages to track this down) Shouldn't progress stop us setting variables like return: ???
