I´m no Clipper programmer at all, but what exactly "does
not work as expected" under DR-DOS, and what kind of
"larger program" is this you are speaking of?

Without any clue on what goes wrong under what conditions,
I´m afraid, we won´t be able to help tracking down the issue
and fixing it.

Can you step by step comment out other parts (for example,
configuration stuff) of the larger program until the operation
works as desired. If you can isolate a more specific trigger
condition, I will probably be able to help.

Since you call COMMAND.COM, it might be important
to know the contents of the %COMSPEC% and %PATH%
environment variables.
Does the "large program" have any means to override
default settings as they are in place in the small
program?
Maybe a problem with too less file handles available?
Try omitting the "> NUL", but if this would not solve the
problem, I suggest to replace this by ">\DEV\NUL:",
anyway.
This might be just a syntax issue of Clipper, but why do
you use "AV_DIR" in dirmake(), and "&AV_DIR" in the
other commands? I am assuming that something with the
file copying does not work, what happens if you replace
this by, for example, simple DIR or ECHO commands?
Are they executed correctly? What happens if you replace
the "dirmake(AV_DIR)", which presumably is used to
create a directory, by something like "RUN MD &AV_DIR"?

Hope it helps,

 Matthias
