REXX cgi scripts with Apache under Win2K

I think the problem I'm having is getting the Apache server to recognize
the REXX cgi scripts as being REXX, and using the interpreter to execute
them...

All righty, I found the directive in the httpd.conf that I had to enable
for Win32. I also registered the REXX interpreter rather than the REXX
Workbench to process *.REX files and renamed all of my .CMD to .REX.
Now I just have to work through the environmental differences as you've
pointed out. For one thing, the CHARIN function seems to be behaving
differently than I'd expect. Ah well...

CHARIN should be compatible. About 4 years ago I migrated a 11,500 line REXX
from OS/2 to Windows. I had to change one line (a call to stream that was
unexpectedly causing the program to hang).

I suspect that your problems are more related to differences in the way
Apache works. Since I'm more familiar with IIS, I'm going to have to
recommend you try an Apache forum for assistance on Apache configuration and
its CGI implementation. One of the nice things about IIS and OO-REXX is that
you can code in-process ASP pages in OO-REXX (this yields better performance
than CGI).

Okay, I found two things that are different already. See these three lines:

Call SysFileTree root || '*.jpg', files., 'F'
index = Random(files.0 - 1) + 1
Parse Value files.index With . . size . filename

For some reason, the "filename" variable above ends up with a leading
space. This is what's causing the CharIn function to fail. I added two
lines:

l = Length(filename)
filename = Right(filename, l - 1)

And this seems to have fixed the problem. I also have to add the
following line to the beginning of every REXX cgi script:

#!c:/program files/objrexx/rexx

Or Apache attempts to invoke the Object REXX Workbench to invoke the
script, and not the interpreter. This despite the fact that I did
associate the .REX extension with the interpreter and NOT the workbench
in the registry.

I seem to be on my way (thanks to Mark and to my friend Herman who
responded in personal E-Mail).

I always manage to do things the HARD way. Scratch those last two
lines. The "Strip" function will work better...<!-- ~MESSAGE_AFTER~ -->

well we use both OS/2 (Classic REXX) and Windows (Object REXX) here and
I just tested the lines above. I get a filename with a leading space on
either Operating System. Maybe there is a change in in the charin
function, but I can't find a difference in the sysfiletree and/or parse
statements.<!-- ~MESSAGE_AFTER~ -->

Perhaps

Parse Value files.index With . . size . filename .

A short while ago I became aware that Jaime A. Cruz had written:
 >l = Length(filename)
 >filename = Right(filename, l - 1)

As well as strip, which another has suggested, you can also do the above
using the substr function:

filename = substr(filename, 2)

Actually, you should have had the leading blank(s) on OS/2 as well...
Strange.

yes, but it happens also to me... I think that something has been
changed at some fp level for os2 (warp4) in the way arg is parsed.
I remember adding "strip(file_var)" after parsing arg because charin
for file_var was not working anymore. Unfortunatly I don't take any note
thinking only to my user error, but who knows...
Not very helpful anyway, I agree...
