Interesting point about not calling exit, which is what I do - and seems to
work O.K. I might change it anyway.
My problem lies in the fact that after calling the Perl scrip %errorlevel%
will ALWAYS be equal to 0, no matter what the Perl script exits with. But if
I run the batch file from the command line, the after the Perl script the
errorlevel is correctly 0 or 1.
