Hi Gary, thanks. Can FM/2 be scripted? I need to automate the
extraction.

Good thinking and nice try (and excellent disclaimer). But it didn't
work. I tried */* also.

But SUCCESS using your idea with PKZip!!

pkzip /extract /exclude=*\* somearchive.zip

works very nicely, thank you very much. :)))

You win a free lunch.

Okay, this is a good concept. And a good article, Dallas, I had missed
it.

For production work I'm worried that a field might occasionally be blank
(I've seen FAT files without a date or time). And dropping the -Z might
help (less output fields).

I think Rexx Tips & Tricks (rxtt* on Hobbes) has some additional info on
writing Rexx filters.

The difficulty with Rexx is the different flavors; I don't want the
thing to break if I run it on a machine which uses Object Rexx, or on a
machine with an early FixPak which doesn't include some of the Rexx
routines which were added later.

I don't have a port of xargs.

Thanks, all.
