Re^3: Use of uninitialized value

      my $numerator;
      my $denominator;
      if ($indicator eq "SH")   { $numerator   = $last_element; }
      elsif ($indicator eq "SL"){ $denominator = $last_element; }
      else { ... }

      if (($numerator > 0) && ($denominator > 0)){ ...

The first time you execute the loop, $numerator or $denominator may get initialized, but never both. Therefore you get the error message Use of uninitialized value in numeric gt (>) at New_program.pl line 535.

I think you're right, but that would not explain his comments works here/ does not work here, the error would be the same at both points	[reply]

I wouldn't bother wasting your time trying to find an explanation for their comments, they've clearly spent no time debugging the problem or actually reading their code, why would the comments have to make sense?	[reply]

`if (($numerator > 0) && ($denominator > 0)){ print "..."; # (print) do +es not work here` [download] The condition will never be true, as at least one of the variables is `undef`. Therefore the `print` will never be executed. I assume that this is the reason for the comment `does not work here`.	[reply] [d/l] [select]
