If you're talking external program calls then you're basically correct.  MI
is the exception as it can pass/receive parms by value.

It sounds like MQ series uses an ILE procedure interface.   I would expect
large parameters like a buffer to be passed as a pointer.  Not very
efficient to pass a buffer by value.   The buffer parm is likely defined as
either a "pointer by value" or a "varsize field by reference".   Actually
both of these are the effectively the same (pointer to data).
