That's cuz system() and friends follow the syntax of the One True
Shell, the Bourne shell.  (Csh is a
hack-turned-least-common-denominator, sorta like VHS tape and
processors that end in 86, but that's another story...)  All Unix
hackers should learn the syntax of /bin/sh and /bin/ed, to see where
all these nifties actually started.

Enough motherhood and apple pie.  The answer to your question is:
	open(FH,"program 2>&1|")

print "Just another Perl hacker," if "there's nothing better to do";
