If MerryMonk is after the built-in constants, my reply is barking up the wrong tree. The code to get them is available from the ActiveState site, but I reproduce it here:

use strict;
use Win32::OLE;
use Win32::OLE::Const;

my $xl = Win32::OLE::Const->Load("Microsoft Excel");
printf "Excel type library contains %d constants:\n", scalar keys %$xl
+;
foreach my $Key (sort keys %$xl) {
    print "$Key = $xl->{$Key}\n";
}
