Rational Developer for System z
Enterprise COBOL for z/OS, Version 4.1, Programming Guide


Running COBOL programs under UNIX

To run COBOL programs in the z/OS UNIX environment, compile them with Enterprise COBOL or COBOL for OS/390 & VM. The programs must be reentrant, so use the compiler and linker option RENT.

If you are going to run them from the HFS, use the linker option AMODE 31. Any AMODE 24 program that you call from within a z/OS UNIX application must reside in an MVS PDS or PDSE.

The following restrictions apply to running under z/OS UNIX:

You can use Debug Tool to debug z/OS UNIX programs in remote debug mode, for example, by using the Debug Perspective of Rational Developer for System z, or in full-screen mode (MFI) using a VTAM® terminal.
