If a one-liner doesn't do what you expect, take advantage of strict and warnings to get Perl to tell you what's going on: % perl -Mstrict -we 'my $i="123.52.32.1"; my $j=45; my $b="$i_".$j*2; print $b, "\n";' Global symbol "$i_" requires explicit package name at -e line 1. Execution of -e aborted due to compilation errors. -- Peter Scott http://www.perldebugged.com/ *** NEW *** http://www.perlmedic.com/ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
