I have the following code snippet: 
foreach(@rec){
  if(/^(\d)(\d{5})(.*)$/){  #rec type, itemno, value
    $num = abs $2;
    $ival = $3;
    # Vrx handling
    if($1 == 1){  #vrx
      $vrx = abs($num . $ival);
    }
and I occasionally get the warning:
'Use of uninitialized value in numeric eq (==) at convert.pl line 240,'
Line 240 is, needless to say, the $1 == 1 line. If I add 'print $1' just above the line, I can see that it has a numeric value, so why and how (given the RE) am I getting this warning?
Any ideas?
Ta.
