I have just started learning Perl. I am developing a small quality check module for JATS XML.

While my Perl program is giving the desired output when executed as a standalone .pl program, it is giving me error as described below, if I execute the same program as package, packaged using PAR (pp -o file.exe file.pl).

Can you please let me know what may be the mistake I am doing in compilation? How can I avoid the error so that the packaged exe gives the same output (given below) as .pl execution.
