My solution is wrong, but for different reasons. eq cannot replace ==:

$a = "01000";
$b = 1000;

printf "\$a eq \$b : %s\n", $a eq $b;
printf "\$a == \$b : %s\n", $a == $b;

use strict; has no bearing on comparisons. What you are thinking of is use warnings;, which will warn about non-numeric values being compared with ==.

Re use warnings rather than use strict - thanks for the correction. Likewise, you are right about the "0100" not being equal to 100, which is what I meant about being sure that the values are represented internally as numbers. So if you said: `$a = "01000"; $b = 1000; print $a eq $b ? 1 : 0; > 0 $a=$a+0; print $a eq $b ? 1 : 0; > 1` [download]	[reply] [d/l]
