I'm doing some RPG programs' development and I found that some of these RPG

confuse that they still working even the number of the parameters are not
match, for example, RPG A has 5 input parameter and its caller CL B only
gives it 3.
As long as no attempt is made to _access_ the unpassed parameters then it will not cause a problem. I would guess that there is some logic in place that ignores the last two parameters if a specific value occurs in one of the first three.
Ideally the program should be testing (%Parms) the number of parameters passed and issuing an error if more than the number passed are required. However it is not at all uncommon for a sloppy programmer to just ignore the possibility of such an error and rely instead on the green-screen-of-death.
