1) you need a chomp to strip the newline symbol,so it should be, $x=<STDIN>;chomp $x; $y=<STDIN>;chomp $y; please don't use $a,$b as variable names. 2) Perl use '.' for strings connection,not '+'.So you need, $c = $x . ' ' . $y; 3) You may need to always add 'use strict' and 'use warnings' at the begin of scripts,like, #!/usr/bin/perl use strict; use warnings; ... -- Jeff Pang - [EMAIL PROTECTED] http://home.arcor.de/jeffpang/ -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
