You've found the right way !

RTX * is similar to RT on/RETRN. RTX terminates the current "Invocation".
DEACTPG * is similar to LR : it terminates the program "Activation"

When you first call a MI pgm (or any OPM one) you implicitly activate it
(ACTPG) *AND* invoke it. It means that until you use DEACTPG your pgm is
still activated and its statics data are keeped from calls to calls.
Invocation lets you use these statics data (scope is current activation, its
something like global variable) and use automatic data which are something
like local variable (the scope is the current invocation). You define your
pgm data (scalar or pointers) as automatic by adding the AUTO keyword.
Without this keyword pgm data are implicitly STATIC.
