Start rewriting the application *now*. Without the source code, all it
takes is one change of computer architecture or one incompatible OS
upgrade, and you won't be able to run your app at all. Don't wait until
this is about to happen; do the rewrite while you still have plenty of
time to compare results with the old version and make sure you've got it
right.


(Decompilers have been discussed in this group. I don't recall what the
consensus was.)

[Except in rare occasions with highly stylized code, I've never seen a
decompiler that was much more than a disassembler with a little syntactic
sugar. I agree that in the long run there's no substitute for rewriting
the program to do what you want it to do. -John]
