Ohhh! That's what I hadn't grokked. That's interesting indeed. OK, so IF it's a C program for DOS, you can run it in this z/PDOS environment. Got it.

You are required to recompile your "PCDOS" programs with gccmvs to produce S/370 code. If the PC had used the S/370 instruction set instead of the 8086 instruction set, what would you expect PCDOS to look like? This is it, basically. Or you can run z/PDOS-generic standalone. It's the same application executables being run. gccmvs etc. In the same way that z/OS and z/VSE use different executables, z/PDOS-generic is another OS. But "inspired" by PCDOS. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
