The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

No, you're thinking of program calls; the parameters to programs are
passed as an array of pointers (but without the operational descriptor).
The parameters to bound procedures are passed individually. When you
pass a parameter by value, the OS really does copy the entire parameter
value as part of low-level parameter passing. (This is additional to
any copying that the RPG compiler does to create temporaries due to type
or size differences; that _is_ usually the same for CONST and VALUE.)
