Determining the CPU time limit

The time limit for using a shell is the same as the TSO/E timeout. In determining the time, the system does not count the processing time for shells running in separate address spaces or processes forked by the shell. If you specify environment variable _BPX_SHAREAS=YES, then the shell processes and possibly one shell command are created in local processes. The CPU time consumed by local processes comes out of the TSO/E address space's time limit.
