How about something like this? Or did you want gawk instead
of perl for some reason?
#!/usr/local/bin/perl
use strict;
my %combos;
while (<>) {
chomp;
my ($mainno,$subno,$asciinoa,$asciinob) = split /\s+/, $_, 4;
if ($asciinoa > 128 && $asciinoa < 255 &&
!($asciinoa >= 195 && $asciinoa <= 255)) {
$combos{"$mainno $subno"}++;
}
}
foreach (sort keys %combos) {print "$_ $combos{$_}\n";}
