What is the difference between:

open (MPRINT, "$mconn|") or die $!;

and:

open (MPRINT, "|$mconn") or die $!;

...$mconn is some unix program with parameters The first line works, the second one doesn't. I don't know what the difference is. I went to a web page, and they said it was the same thing, but if one works and the other doesn't...it seems like they aren't the same thing. Does anybody know the difference? Thanks timmyb85
