Process initialization initializes environment variables from /etc/environment. 
There is no requirement any shell environment (e.g. bash, csh or ...). Are you 
saying that PGM=BPXBATCH,PARM=’PGM program-name’ invokes a shell to create the 
environment variables? Most notably $PATH. Granted that shells simplify adding 
environment variables but programs are able to add environment variables 
without using export, setenv or ???.
