Of course, you can always have VB output the results to a text file and then
have Perl read it. I think that would probably be the simplest way to do it.

Close. I don't see why you're passing the return to an array rather
than scalar (@ rather than $), since it should just be an integer.
You're also capturing the output of the program when you use backticks,
rather than the return code, which is captured using system().
To execute and capture the return code of a program, I'd use:
$return_code = system('program');
.... but that assumes that the 'program' is something that can be entirely
executed from the command line and returns a useful return code - I
don't have familiarity with VB, but my short experiences seem to suggest
that this would be rare.
*awaits correction from Japhy* :-)
