I'm a relative newbie to Perl, and I've been searching around the Monastery, the Llama book and the Camel book, and I'm not getting why my variables are going out of scope. I parse command line values and set a scalar variable defined in my Main (though Main is not named, just using the defaults). I then call a subroutine to open files, and other routines to process the files. I'm using 'our' in the sub where I reference the variable, but it is still out of scope sometimes.

I appreciate any help anyone can provide

Kelly

Here is a snippet from the file: 

use strict;
use warnings;
use bytes;
#...
my $showPUV = 0;
my $showPUVdesc = "";

# Call a sub, which calls a sub, etc... 
# The Main doesn't end until all files have been processed

sub FilterMessage {
  $Line = $_[0];
  our $showPUV;
  our $PUV;
  our $Report;
  our $EVENTNAME;
  our $EVENTTEXT;

  Clear_Arguments();
  Parse_Messages();

  ## IF we care about the PUV and it is NOT our PUV, don't show it
#  if (( defined $main::showPUV ) and ( defined $main::PUV )) {
    if ( $showPUV != 0 ) { ## This is undefined sometimes!!
      if ( $showPUV != $PUV ) { return $FALSE; }
    }
#  }
  ## else this test is OK, the line can be shown at this point

  if ( $Report eq "events" ) {
     if (( bytes::length $EVENTNAME > 0 ) or 
         ( bytes::length $EVENTTEXT > 0 )) {
       return $TRUE;
     }
  }
  elsif ( $Report eq "comms" ) {
     ## need to do some more work here
     return $TRUE; 
  }
  else {
     return $TRUE; 
  }
}
