C parameters are always _officially_ passed by value, but I think it's
convenient to think of a "pointer-to-sometype passed by value" as
"sometype passed by reference".
int i
integer passed by value
int *p
pointer-to-integer passed by value
or
integer passed by reference
or, for maximum confusion
integer array passed by reference
It is especially useful for RPG programmers to think of sometype*
parameters as being "sometype passed by reference". The RPG prototyped
parameter for "int*" should be coded as a 10i by reference, not as a
pointer by value.
