footpad, I admit up front that I don't use MS-(DOS|Win3?) batch very oftern (I"m a Unix SA), but couldn't you simplify the task simply by having two batch scripts, one which called Perl, and one which called Perl and redirected the output.
c:\devt\perl\bin\perl.exe %1 %2 %3 %4 %5 %6 %7 %8 %9 > stdout.log
No need for all the extra checking. Frankly, the batch processing isn't all that powerful. I look at the alternative example and cringe. (Not at you, but at the lack of power of the batch.)
"Beware of false laziness" is the council in one of the zoo books. I think this may be a case of it. 8)
BTW, thorough doing of your homework. Still a ++ for good forethought.
