Though I don't use Linux myself, I have an idea:
You use the pipe ( | ). So the Shell first executes "echo 12345" and stores
the output of the console (here: 12345).
Then it executes the second command in the pipeline ("rebol/rebol -q
hello-world.r") and attaches the previously stored value (12345) as an
command line argument. So de factto the shell does the following:
rebol/rebol -q hello-world.r 12345
There might be an error in this call. Rebol stops executing the script
without quitting the interpreter ("hangs"). But you don't see the error msg
as you started the interpreter with the quiet option set. Try and start
Rebol without -q.

Ok, just can tell you about AmigaOS:
characters:
You can use any characters of ASCII-8 character set except ":" and "/" and
ASCII-Code 00 .
[] . - % etc. can be used in filenames. But you must be careful as some
characters have special meanings and are interpreted by shells. e.g. if you
create a .jpg file with rebol and save it as mypic#?*.jpg and you have an
image viewer myviewer that supports pattern matching you get into trouble if
you start it from shell as * resp #? are placeholders for the pattern. If
you save a .html file and show it with "openurl
file:///documents:myfile#?*.html" you will not get any problem as openurl
doesn't support pattern matching.
If you don't start a file using a shell but using your desktop or a file
requester you will not get any problem.
Which special character is interpreted as a shell command depends on the
shell you use (AmigaShell,WShell,CSH,KSH,ZShell etc).
If you want to be careful I ' d suggest not to use < > [ ] ( ) : / zerobyte
" ! | ~ * # ? ; ' $ % `
maximum length of filename:
depends on the used filesystem (8+3,30,107 characters).
case sensitivity:
depends on the used filesystem (case sensitive,non case sensitive except
foreign characters like äöü etc.,non case sensitive for all characters)
filename extensions:
depends on the used fielsystem. For MS-DOS 8+3 filesystem you need to have
an extension that begins with a "." ;
other filesystems don't need one. "." is not a special character.
Hope thsi helps.

[REBOL] Email standard definition ?

If just one, you might try something like that: myfile: read %filename search_for: rejoin [newline newline] replace_with: newline replace myfile search_for replace_with for the case that there is more than one empty line at once: don't know either. ciao, Jean

But put only the function definitions into it. But only those who are actually used in your project. As 'do' runs the whole script, all function definitions will be evaluated at runtime. If you would like to build your own function library to be used in several projects, then it is recommended to have a separate include file for every function. ciao, Jean

And I doubtit's possible to write a good syntax highlighting module for rebol at all. In most languages there are exact naming rules, e.g. in my favourite language E: first two literals of word are upper case->constant first two literals of word are lowercase , not ending in a ( ->variable first literal upper case, second one lower case -> standard E function or a system function ... But with rebol ? imagine the syntax parser finds a word like Öffne_Datei : what is it ? A variable, a function ? ciao, Jean
[REBOL] using environment variables Re:(3)
Hi, I don't think there's a general way to set/get environment variables in REBOL as different OSs use different mechanisms to provide env vars. Under AmigaOS global env vars are ascii files located in the ENV: path . One could write following functions to set/get them (not tested yet). func set [varname varcontent] [write to-file rejoin ["/env/" varname] varcontent] func get [varname] [to-string read to-file rejoin ["/env/" varname] ] usage: to set a global variable $bla to "This is a test" : set bla "This is a test" to get it and store it in a rebol var called gotit: gotit: get bla Probably there are other OSs that use a similar mechanism, try it.

Now it works :) So if I use a block within a block I need reduce to tell rebol to evaluate the embedded block. But why do I need rejoin in this case ? join "" [reduce block1 ""] also worked as I tried it. Theoretically, rejoin ["" block1 ""] should work,too. The Rebol doc says: Rejoin: Reduces and joins a block of values. ciao, Jean

[REBOL] script needs more than 100 MB of ram , why ??
i wrote a program that reads the content of a binary file and converts each byte to a string containing its ascii value. and saves these strings to a textfile (separated by newline s) e.g. imagine a file with this content: Hello the program then creates a file with the following content: 72 101 108 108 111 ; my program includes this code: a: "" ; init an empty string readtomem: read/binary %dummy.exe ; read the whole file dummy.exe into memory foreach num readtomem [ a: join a [num newline] ; add the ascii code as string to a, then add a newline to a ] write/append %dummy.txt a; if %dummy.exe has a size of 88.000 Bytes then my script needs more than 100 MB of ram at runtime !!! the problem seems to be the combination of a loop (foreach) and a: join a any ideas to replace a: join a ... with a less memory consuming alternative ???
