Bruce and Nikolai,

Thanks for the replies. I am referring to a call to a C program from elsewhere, like a CL or RPG program. I've not dealt with C for a looong time.

Assuming that you are refering to a call to an external program (#pragma
linkage) then per the C/C++ Compiler Reference (

The compiler issues a warning message and ignores the #pragma linkage directive if:

v The program is declared with a return type other than int or void.

v The function contains more than 256 parameters.

What is the maximum number of parameters on a C program call on the
IBM i system? We are at V6R1. Is there a documentation link that
someone can point to that notes this?
