in thread Perl module error

Maybe there is some problematic whitespace in your .pm file:

cat -A

You should download the code from your post, just like I did, and paste it into a new file.

    I did what you said, downloaded it and replaced, and it worked! But then when I add my additional code to the file, I get error again: "" did not return a true value". So what is this whitespace problem? White spaces should be ignored by perl, and I don't have new line after 1; Is it about the newline character? I'm using Notepad++ on windows.

      So what is this whitespace problem?

      do like toolic told you and find out using cat -A file

      $ cat -A foo sub ^Mfoo ^M{ 1 ^M}^M
      ^M is \r aka CR
