Hi Sophienz,

Please let me know if I can make things clearer.

Post a complete, working test script that shows your problem. Fine if it needs a 251-element array, just make one:
push @long_list, $_ for (1001..1251);

Cut out all the code that doesn't affect your problem. Start a new test script with just the loop that is giving you trouble.

Isolate the problem. Make it happen when you don't have your data in the script. That will prove whether or not the data are to blame.

The monks don't need to see all your code, but neither do they need to see an arbitrary subsection of it. They do not need your variable names (unless that is the problem) and they do not need your specific data (unless that is the problem). When the problem is programming, your logic, or, Mysteriously Unidentified, the monks need a small, self-contained, working test script that demonstrates the problem.

The benefit for you is that while you are making the test script, you will usually discover the problem and see how to fix it. And if not, you'll present the monks with something with which they can help you.
