Hi poj. Thank you for your assistance. You guys/gals are advanced here. I replaced the `my $infile = $ARGV[0];` with `my $infile = C:\Users\... \abc.txt;` Similar with the output file. I knew it was not right to do this but I did not know what else to do. How do I get my input file read in and the output into the output file? Again, thank you very much for the code and assistance. jlb333333	[reply] [d/l] [select]
