Hello, I have a 355 line code that takes about 3 hours to run. I find errors like "Use of uninitialized value in subroutine entry at meth_analysis.pl line 311" I have 4 different arrays on this line which could have been uninitialized. How can I set perl to change this warning to something like "Use of uninitialized value $hash{key1}{key2} in subroutine entry at meth_analysis.pl line 311" in other words, how can I get the uninitialized warnings to tell me which value is uninitialized? To compensate for the vague warning, I have littered my code with "if(!defined($var))" but I would prefer a better solution than this. thanks, -DEC
