Any easy way of doing this? (I got a loop, but it feels there ought 
to be a more elegant way)
     a: "123123123"
     b: "12312345678"
     print skip-common a b
     "45678"      ;; string after common part of both strings

Hello;
  How do you convert a letter (ASCII) to it's hex equivalent?

  I've tried to-hex but it wants an integer!?  You would think it would 
  be easier than:


print to-integer to-string to-hex to-integer to-decimal to-char "a"

which works but there has got to be an easier way.

>> to-hex to integer! #"A"
== #00000041

Gordon, your method only works for chars than happen to map to decimals. 
 Try this for an error:

print to-integer to-string to-hex to-integer to-decimal to-char "M"


Variant on Tom's to produce the same result as yours (may not work 
with 64-bit REBOL)
     form skip to-hex to-integer first "a" 6

Thanks Tomc and Sunanda

>> copy/part tail to-hex to integer! to char! "Z" -2
== #5A

unfortinatly for me we dont have a 64 bit rebol

Does anyone?

or unicode

not that I know of

Thanks again for your help

Quick work there Gordon:

http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=char-to-hex.r
Thanks for the name check :-)

And I see you've solved the potental 64-bit / variable hex problem

Well actually Tomc made the suggestion.

Sorry for the slow reply but if I leave Altme open it keeps stealing 
focus from my coding program .  I have to shut Altme down so I can 
work.

Here's another odd one that has be puzzled

(Notice that appending something to the Writefile variable, also 
appends it to the DateStr variable!  Very Strange!)

>> WriteFile: "WriteFileName_2005-05-07"
== "WriteFileName_2005-05-07"
>> DateStr: skip tail WriteFile -10
== "2005-05-07"
>> Success: append WriteFile "_Parsed.txt"
== "WriteFileName_2005-05-07_Parsed.txt"
>> probe DateStr
2005-05-07_Parsed.txt
== "2005-05-07_Parsed.txt"

Nevermind.  I think I should have used a copy of Writefile.  DateStr 
must be a subset of  WriteFile variable because of the reference 
to it's tail.

Yep, it just  needed a copy as in:
>> DateStr: skip tail copy WriteFile -10
== "2005-04-11"

gordon:  home-icon - settings - options -unset  "activate window 
on new message"

Thanks Tomc; that should do it.

how to decode this url ?

    result

sunanda: i can only think of:

>> index? find (as-binary a) xor as-binary b complement charset "^(00)"
== 7

though, i'm not sure it's an easy way, and it is probably overkillif 
a and b are "big".

another option would be to try with parse, though it's gonna boil 
down to some kind of loop anyway.

>> parse a [any [(char: b/1) char (b: next b)]]
== false
>> b
== "45678"

is your callback function returning a value? i think it should return 
true normally, or false if you want to cancel the download.

Use request-download as a guide. It has everything you need to know. 
you should be able to substitute read-thru with read-net if you wish.

O'k. My mistake are offen do not tell what is my target. So it is 
to get working status bar in a layout. As I understood it is possible 
by read-thru.

Thanks Gabriele. It was the reason. But to continue regarding status 
bar functions fired by read-thru. Than it is a problem just to kBox/image: 
 read-thru/progress myUrl :myProgr . It is possible just by using 
local file i.e. kBox/image: read-thru/to/progress myUrl %tmpImg.png 
:myProgr

How then to calculate data for progress bar ( decimal from 0 to 1 
)?
Or how to get total bytes?

Janek. request-download has the example callback you need. View its 
source. here is a snippet. Where prog is the progressbar and stat 
is a label in your layout and stop is a value that controls that 
should be be set false outside of this func to start with, and can 
set to true via a cancel button to force a download to stop before 
completion. 
func [total bytes] [
        prog/data: bytes / (max 1 total) 
        stat/text: reform [bytes "bytes"] 
        show [prog stat] 
        not stop
    ]

Thanks Allen!
The problem was so obvious that I did not think about it ;-)

just it is impossible to know what size of image will be that is 
coming from a cgi process with many parameters.

A easy job for REBOL... http://www.eyon.com/. I can't believe this 
tool needs to be 4mb zipped.

i like this little function and cant find a good name.
your: func [offset value] [
	if value [value/:offset]
]
usage:
 your 'facet get-style 'field

its sometimes more readable IMHO than putting the interesting word 
far at the end of line.
but i find no good name.. any suggestions?

Help peoples..

I have the following..
  x: [a b c d]

  foreach y x [ set y make string! {} ] ;make them all empty strings.
then I process/append info into the different groups a,b,c,d.
Now, I want to write each string/list to a file of the same name.
i.e.
  foreach y x [write to-file join y ".txt" ??GETVALUE?? y]

Can someone clue me in on what I do at the ??GETVALUE?? position?

Thanks peoples.

foreach y x [print [y get y]]

... so the missing ??getvalue?? is just get
