Hello zing,

When I take your original script, make the change I described, and run it on the file “p17226.csv” (which I downloaded from http://qfs.mobi/f1508588), I get 848 lines of output which begins and ends as follows:

16:31 >perl orig.pl
Enter file name:
p17226.csv

Your output format has changed, have you altered the script since first posting? If not, it looks as though you’re going to have to debug the script yourself, on your own machine, to find out exactly what’s going on. The tutorial perldebtut will help you to get started.

Hope that helps,
