in reply to use strict;

monks, sorry about not attaching my code here it is.

#!/usr/contrib/bin/perl -w use strict; my $a="5.0"; my $b="5"; print "Are these variables equal as numbers? ",$a==$b,"\n"; print "Are the variables equal as strings? ",$a eq $b,"\n"; print "These variables are equal as strings\n" if($a eq $b); print "These variables are equal numerically\n" if($a==$b);

    When you're running perl script.pl you are using the version of Perl from your path. This seems to be fine.

    When running ./script.pl you're using the version in /usr/contrib/bin/perl. Looks like that's Perl version 4. to confirm this type
    /usr/contrib/bin/perl -v at your command line.

    To fix it, find out which version of Perl is on your path by typing which perl and replace the /usr/contrib/bin/perl in your script with the results of that command.
