The company that I work for uses the OS/390 operating system. However we still have programs from the early 70's that are still coded in OS/VS Cobol (68). I have systems with assembler drivers & cobol 68 called modules that use the SPIE and SNAP macros to control & recover from abends, both program & system issued. I have the OPERTUNITY of researching the changes needed to bring these programs up to 370 & then to OS/390. I have converted some stand alone cobol 68 programs to 370. I would appreciate any help in how to upgrade/change from the SPIE/SNAP macros to the equivalent 370 comands. I have been testing with the CEE3DMP subroutine & have a question about it's operation that I can not find in the IBM manuals. After you issue the call and the subroutine returns to the program that issued it, just where does it return control too? In other words how does it decide what code to execute next?
