You are correct and thank you for pointing that out. Unfortunately, I am still having problems though. In an attempt to make the post easy to read, I left out some of the code and that makes the answer thus far impossible as far as I can see. Here is how my code should have looked: `foreach my $line (@array) { if ($line =~ /mail: /) { my $mail = substr($line, $+[$#+] ); print "mail=$mail\n"; } }` [download] With that, I see no way to use the single quotes as suggested. Any other possible solutions?? Thank you again.	[reply] [d/l]

What do you get if you capture? `if( $line =~ /^mail:\s+([\S]+)$/ ) { my $mail = $1; print "mail=$mail\n"; }` [download] Dave	[reply] [d/l]

The '@' isn't a problem when you read it from a file. Only if you're using it in a double-quoted string. For example: `$ cat t.pl #!/usr/bin/perl use strict; use warnings; my @array = <DATA>; foreach my $line (@array) { if ($line =~ /mail: /) { my $mail = substr($line, $+[$#+] ); print "mail=$mail\n"; } } __DATA__ This @ should be just fine mail: this @ should also be fine $ perl t.pl mail=this @ should also be fine` [download] ...roboticus When your only tool is a hammer, all problems look like your thumb.
