got it to work.. but one more Q
#!/usr/bin/perl -w
open(FILE, ">", "dataFile");
while(<FILE>) {
chomp;
if ($_ =~ /^[[:alpha:]]+$/) {push @stringArray, $_; }
elsif ($_ =~ /^\d+$/) {push @intArray, $_;}
}
close(FILE);
$lengthArray=@intArray;
for($i=0; $i<$lengthArray; $i++) {print"\n$intArray[$i] $stringArray[$i]";}
print("\n");
exit 0

Using the code you provided I was able to see what needed to be done.. Thank you. However, I have a small question. To pull in the alpha char I was unable to use \w and went with what you had [[:alpha:]] otherwise I would pull in all entries.

So here is the question... what is the difference between \w and :alpha:
