Should running the above from the command line make a difference? I ran
them both entering 0 each time and I got 0 back. This is what it looks
like:
[EMAIL PROTECTED]:~> perl -e 'if ($_ = <STDIN>) { print; }'
0 <---input value
0 <---returned value
[EMAIL PROTECTED]:~> perl -e 'if (defined($_ = <STDIN>)) { print; }'
0 <---input value
0 <---returned value
