I dont think that you will face any problem.
If the 3rd parameter is passed by reference (it is a pointer to the space occupied by the parameter that is passed to PGMA), it is ignored by PGMA because it is not defined in PGMA *entry Plist
If the 3rd parameter is passed by copy, then again, a copy of the parameter value is made and a pointer to that copy is passed to PGMA and is ignored as before.

Objet : Calling a program with more parameters than are defined
PGMA has an *entry plist with 2 parameters, all fixed C-specs.
PGMB calls PGMA with 3 parameters in the call.
Both programs are RPGLE.
In my testing, there were no apparent errors.
Is there a concern that the data passed in the 3rd parameter may corrupt memory in PGMA?
This is somewhat an academic question. PGMA currently has two *entry parms defined. Currently, in development, it is being modified to add a third parameter. (FWIW, it will be optional because many programs will continue to call the program with only two parameters. %PARMS is used to determine the number of parms passed.) There is a web app that calls PGMA with two parameters currently, but is being modified to call it with three parameters.
Since web app deployment and Power i app deployment are on different schedules, the web app may be deployed before the Power i app. Hence my question.
