This is a MicroFocus IBM developement platform. It tries to emulate a
mainframe environment. It has a catalog like a mainframe. It handles files
like a mainframe. I believe if I can come up with a way which would work on
the mainframe, it should work on the MicroFocus platform. As I stated
earlier, it runs IBM JCL and PROCs. So I am looking for an answer for an IBM
mainframe. If that won't run on MicroFocus, they have a problem.
