'print' does NOT normally append a linefeed/cr pair unless you tell it to. Now, on a linux Mandrake 7.2 box: bash-2.04$ perl -v This is perl, v5.6.0 built for i386-linux Copyright 1987-2000, Larry Wall Perl may be copied only...etc... bash-2.04$ perl { my $i = 1; print $i;} bash-2.04$ Note that nothing printed. This is incorrect, however I bet I can make it work: bash-2.04$ perl { $| = 1; my $i = 1; print $i;} bash-2.04$ Hmm. Looks like perl is closing the output before flushing it. bash-2.04$ perl { $| = 1; my $i = 1; print $i ,"\n";print $i , " asdf";} 1 bash-2.04$ I'd say its a bug in something somewhere. However, try this: bash-2.04$ perl { $| = 1; my $i = 1; print $i ,"\n";print $i , " asdf";my $foo=<>;} 1 1 asdf ..I type here... bash-2.04$ Yup, its a bug... ;-) Rusty Carruth Email: [EMAIL PROTECTED] or [EMAIL PROTECTED] Voice: (480) 345-3621 SnailMail: Schlumberger ATE FAX: (480) 345-8793 7855 S.
