If you
specify RETRN in called program, the *INZSR will not execute again.
Reason: The INZSR is used
to "initialise" the environment for the execution of your program by
setting/resetting variables, etc, however many times it is called. If only
return is used, all the values are held
in memory anyway, so you don't have to initialize everything all over
again. If LR is on at the end, INZSR will be executed again.
