Yep, this is easy in perl #!/usr/bin/perl -w #tested code on 23 July 2004 use strict; my $first = "a"; my $second = "b"; print "\$first is $first, \$second is $second\n about to swap\n"; ($first, $second)=($second, $first); print "\$first is $first, \$second is $second\n"; -- Kind regards, Hal Ashburner -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
