well, this restriction has forced me to come up with: perl -e ' $entry = "willy"; (print /$entry/) while ($_ = "wil"); print "0"' in this test it ends up not getting to print "0", but with a match it works great :) i can apply it properly now when substituting a filehandle for the expression in the while. thank you! >-- >Jeff "japhy" Pinyan % How can we ever be the sold short or >RPI Acacia Brother #734 % the cheated, we who for every service >http://japhy.perlmonk.org/ % have long ago been overpaid? >http://www.perlmonks.org/ % -- Meister Eckhart -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
