Linkage variables during multiple calls

This is a bit lengthy question.

Program ABC has three parameters in procedure division. And statement
CALL 'ABC' using X, Y, Z
is passing all three parameters to ABC.

When I coded next statement
CALL 'ABC' using X, Y
This time I am not passing Z.

And will I be able to access variables present under Z?

not at all...
what happened when You tried ??

most probably You should have got an abend...
the called subroutine expects to receive three parameters and only two were provided

I also expected an abend. But surprised.

It is going good.

Is it like when
CALL 'ABC' using X, Y, Z is done and address exstablished Z in ABC is not lost once the program is completed, and during second call
CALL 'ABC' using X, Y i was able use variables under Z.

FYI..The way program ABC and Caller are linked static not dynamic load. Will this also cause above to work?

Hello,

Suggest you correct the code to specify all 3 variables for each/every call. It doesn't matter that it happens to work now - what would matter is when something causes an abend later. . . Or worse - it runs incorrectly and does not abend. . .
