Hi all,

Can someone help me with setting the current directory?  
My problem is that I want to:

1. check for a file(s)
2. Delete File(s)
3. Write to File(s)

in a directory one below my current postition, such as 
\subdirectory

I can't seem to find a way to get there.  I've used 'cd .\directory',
but this doesn't seem to keep me in the subdirectory.  I've tried
'dir .\directory > filename' and this works but of course doesn't 
actually change the directory and make it current.  I just did that
for testing.

Any help would be apprecieated,
John.

In OS/2 REXX, the directory() function will change both drive and directory in a single call.
 I was able to change to a directory "temp" under my current directory with the statement:

   code = directory("TEMP")

There was no need to reference the current directory (".") although that should work as well.
 What you posted should work, but there may be another problem with the program.  Can you post
a code fragment?

You didn't state what OS you're on, but under OS/2 you use the
DIRECTORY() function. The online help gives an example that
is very similar to what you want to do.

JWRUGO:

   You ask how to change to a directory where you want do things.

   My REXX is IBM's version for DOS.  A simple one-liner seems to work
fine:

      'call cd [target directory]'

   Hope this helps.

This does not word in Regina/win32

Warren's answer is not particularly verbose.  I think he is suggesting
that I use a full path specification on all DOS calls rather than a
CD-relative one.  This will solve my immediate need (thanks), but I'd
still like to have a CD if anyone has any suggestions.

At least using fully specified file names is better than my previous
best solution of the program calling itself in the new directory.

True!  My reply was terse.  The syntax will make you current with ANY 
valid part of the directory structure in any drive you have available.

Take a look for the DIRECTORY built-in function. It's described in TRL
but it isn't mandated there. It DOES work on all implementations of 
REXX for Intel platforms that I've messed around with. (OS/2 REXX, PC 
DOS REXX, and Personal REXX for all Platforms). It might work in 
Regina too.

Perhaps I'm missing the point, but the following three lines get the 
job done for me, in OS/2 REXX:

'C:'
'CD \DIRNAME\SUBDIR'
'START NEWPROG.EXE'

If you need a relative reference, just adjust line two accordingly, 
(skip the initial "\").  I use the full pathname so I can be positive 
I'm where I want to be :).

Hope this is useful.

Sincerely,

John Hopkins
