I prefer pipe-open to backticks because it is much easier to ask for errors, and it works like a filehandle...

unless (open (CMDREAD, "$program $args |")) {
  die "ERROR in executing $program $args: $!\n";
}
else {
  while (<CMDREAD>){
    # do something with $_
  }
  close (CMDREAD);
} # else

But if it really is a big ammount of data, I'd execute it and have it's output writing to a file and then read it from there with
while (<FILE>)
or the like...

Best regards,
perl -le "s==*F=e=>y~\*martinF~stronat~=>s~[^\w]~~g=>chop,print"
