I think you are explaining what, in COBOL terms, is CALL BY CONTENT, not CALL
BY VALUE. CALL BY CONTENT seems to be similar (same?) as what Bernd is
describing in PL/I with the placement of parentheses around the argument. CALL
BY CONTENT (in COBOL) creates a "dummy" variable, copies the
t;,
it copies them in the
reg1 parameter list. This CANNOT BE DONE using the CALL macro. And this
would be
the correct answer to the original question.
HTH,
kind regards

Do not use CO BOL as an exemplar of programming discipline. Cobol rots the
brain.

This messa

the 3rd argument was to show one "passed by reference"; in any case
modifiable by the subroutine.
But where did x and y come from?

I'm guessing he meant "int *k&q
I'm guessing he meant "int *k" rather than " k".

Aren't all parameters in C passed by value? C has no
Can the MVS CALL macro be used to call a C function with "value" parameters
(rather than reference parameters)?
