[sf-perl] Referencing a variable???

[Peter Loo]

Hi All,
 
I have done this once before and can't seem to remember how I did it.
 
I have 10 program variables namely $parm[1-10].  Then I try to check if they are set using a loop like so:
 
  for ( my $x = 1; $x <= $maxParm; $x++ ) {
    my $parmName = "parm" . $x;
    if ( $$parmName ) {
      my ($hardValue, $replaceValue) = split(/~!~/, $$parmName);
      $sqlString =~ s/~$hardValue~/$replaceValue/g;
      }
    }
 
$$parmName has no value.  What am I doing wrong?
 
Thank you all in advance.
 
Peter
