Re^3: Cannot work on second file after reading first file.

Did you try running it with the additions I proposed? They are tests that attempt to get to the bottom of why your while() loop seems to never be entered. That's relevant information.

I added the code you posted and the program ran the same as before. I'm not sure how to set the $ENV{MYSCRIPT_DEBUG} to true. I tried adding the following line before your code, but I guess that's not it? `my $ENV{MYSCRIPT_DEBUG} = 1;` [download] Can you tell me how to set the variable to true?	[reply] [d/l]

Your "environment" is the shell from which you run the script. If you're using bash, you would say, "`export MYSCRIPT_DEBUG=1`" on the command line, for example. Then run the script. On Windows, I think it's "`set MYSCRIPT_DEBUG 1`", or "`setx MYSCRIPT_DEBUG 1`". You could eliminate the "`if $ENV{MYSCRIPT_DEBUG};`" test altogether, but then you would have to remember to remove the line of code later on, once things are working as they should. This is just a convenient way to turn on and off debugging behavior without altering your code repeatedly (which provides opportunities for creating new bugs). Dave	[reply] [d/l] [select]
