in thread reduce line of code

I often prefer setting a default, then overwriting with the validated value:

my $cmd = 0; $cmd = $step_no if $step_no =~ /\A\d+\z/;

    I guess this is what Sun751 meant. His non-working example scopes the $cmd variable to the if ... else blocks.
      OT: just add
      use strict ; use warnings ;
      to your programs, witch would have detected your scoping problem!
