Hi, I have a problem with the BPX1EXM service, specifically with the STEPLIB it uses for the executed MVS program. My program (an LE program written in C, running under z/OS Unix) first forks a child process, which then immediately calls BPX1EXM (=execmvs) to start an MVS program in a specific load library. According to the documentation of BPX1EXM, you can set the STEPLIB environment variable to the steplib you need the MVS program to have, and, in fact, this works up to a point. If I set the STEPLIB environment variable in the z/OS Unix shell before starting my program, then that STEPLIB value is used by BPX1EXM to find the program; that works fine. BUT... if I use setenv() or putenv() or CEEENV() to set the same environment variable to the same value, then BPX1EXM does not seem to pick up this variable; it can't find the MVS program. It makes no difference where I put the putenv(), at the start of the program, before the fork, after the fork... it does not matter. Only if the variable is set in the shell before starting the program, then BPX1EXM picks it up. Obviously, that does not suit my needs, because I need to start multiple programs that reside in different load libraries. Does anyone have an explanation for this behavior?
