Yes, do something like this (assuming a Bourne-type shell; others will have
to help you with csh):

#!/bin/sh

perl <<'EOT' - input.dat
while(<>) {

}
EOT

The "-" means that your script is coming from STDIN. See perldoc perlrun.

How about using awk?

awk '/[01]$/ {print >>"01.dat"} /[35]$/ {print >>"35.dat"}' input.dat
