I'm still trying to crawl to the table to grab the scissors...

So, I've done this and it works:

use strict;
use warnings;


 open my $textfile, '<', 'C:\Users\msmolik\Desktop\PERL test stuff\tes
+tfile.log' or die $!;
   
 while ( my $dtmf = <$textfile>) { 
    if ( $dtmf =~ m/ccParty<(.+)>.+DTMF<(\*\d)>/ ) {
  print "$dtmf\n"; 
}
}
{
  close $textfile;
  }

and was able to do this:

use strict;
use warnings;
print "What is the conference hexidecimal name?\nInput Name:";
my $Conf_Hex = <>;
chomp ($Conf_Hex); 

 while ( my $polling = <$textfile>) { 
    if ( $polling =~ m/VtO<.+> VtTp<(?!0)(\d{1,3})>.+MCfID<0x$Conf_Hex
+>/ ) {
  print "$polling\n"; 
}
}
{
  close $textfile;
  }

Now, I've code that will convert a number in decimal to a hexidecimal. But I can't figure out how to combine that in the second code above to ask for the number then use the hexidecimal output instead of asking for the hexidecimal input.

I guess in simple form, I want the conversion code to ask for a number. I give it 18. The output is 12. I then want to take that 12 and put it in the line of code above in place of the $Conf_Hex value in the "if" statement.

Here's the code for the conversion:

print "What is the Conference IDX?";
my $num = <>;
chomp ($num);
exit unless defined $num;
$num = oct($num) if $num =~ /^0/; 
printf = ("%x\n", $num) ;

Anyway, I'll keep plugging along. Thank you to everyone for suggestions and pushing me in the right direction.
