*Please* read my postings before calling me stupid ;-)
In the first one I wrote that "I got a perl (script) which does .." so
the call to cat is in a script (foreach (`cat $fn`) {..). And I
invoked it from command.com, yes. But after your suggestion I tried it
with bash and, as you wrote, with TMP and TMPDIR set to c:\win95\temp.

But, well, I just *set* it, I didn't *export* it...

Allright, thank you, it was me again, now it works, read u,
