Although I agree that jscript is a more powerful scripting language than
batch, the distance between batch and jscript is of a similar order of
magnitude to that between batch and vbscript.
Had the question been asked in one of the batch-oriented newsgroups, a batch
solution would likely have been given that was simpler and more direct than
your jscript one (or its vbscript equivalent!).
Powerful is one thing, applicability to the task is another. Of course, the
OP's original environment and background might have a thing or two to say
about this as well.
