I am looking to set up my Perl program to run automatically when my MS Windows is booted up. No problem there using Startup, but this program does not respond in the same way to input files. I am guessing that the problem either lies in the use of the system call to another Perl program or the use of Perl modules. Does anyone have experience of a problem like this? It is a bit of a pain to debug this because I can't easily capture the error message. The program works fine when I open up a DOS shell and run it from there.
