RE: how to compare to string variables

[Scot Robnett]

Or even if you don't want them to be identical but just similar in that they
contain the same string somewhere within the variable, i.e.

        $a2 = 'Lambott';
        $a3 = 'fooLambottblah';

        if ($a3 =~ /$a2/) {
         # do something
        }
        else {
         # do something else
        }

or what if you want to match it regardless of case?

        $a2 = 'Lambott';
        $a3 = 'laMboTt';
        lc($a2);
        lc($a3);

        # Now $a2 eq $a3 because both of
        # their values are lower-cased to 'lambott'.

        if ($a2 eq $a3) { # Houston, we have a match
         # do something;
        }

        # Note: We could have done uc($a2); uc($a3);
        # in which case both values would be 'LAMBOTT'
        # because uc converts the string to upper case.

If($a2 eq $a3) { ...}
else {....}

Is this what you want?

Thank you & best regards,
