If you could get the source code for the compiler, then you should update it to be z-exploitative. And then update it to run under linux on z hardware (LPAR or under z/VM). That will let you not just move to current supported hardware, but be able to move forward with IBM hardware.
If you need to move to non-370 related hardware (x86, AMD, Sun) then rewrite it in C on a linux operating system. From there you can recompile, update for any of the other hardware platforms and even for Windows. /Tom Kern Karl Severson wrote: > I need some advice and hopefully someone on this list serve has already > tackled the problem I’m having.
