Hey Dave, Thanks for the advice. Although I am using your code, I am not getting the correct output...

Code I am using:

#!/usr/bin/perl use warnings; use strict; if($#ARGV<0){ die "Usage: $0 <*.txt>\n"; } open(IN,$ARGV[0]) ; $/ = "\n\n"; while ( <IN> ) { if( my( $number ) = m/(\d+)/ ) { s/\b\p{Alpha}+\b/$number/g; } else { warn "Malformed record in input line $.\n$_\nContinuing.\n"; } print; }

Input:

0 ASDF ASEE ASEE 13 DERG DREG 28 QWER QWER 42 WERT WERT WERT 55 QWEASD QWEASD QWEASD QWEASD

Getting this output:

0 0 0 0 13 0 0 28 0 0 42 0 0 0 55 0 0 0 0

Desired Output:

0 0 0 0 13 13 13 28 28 28 42 42 42 42 55 55 55 55 55

I see that it is in this line s/\b\p{Alpha}+\b/$number/g; where the substitution is being made. Is the code referring back to the original 0 in the top left hand column perhaps?
