Chapter 2 Intrinsic Use
You invoke an intrinsic by calling it explicitly from within a program,
subprogram, or procedure. All system intrinsics are treated as external
procedures by user programs and the intrinsics mechanism facilitates the
declaration.
To call an intrinsic, you must know the following information:
* The number of parameters and whether any are optional
* The data type of each parameter and whether parameters are passed
by value or reference
* The calling sequence or order of the parameters
* The functional return value, if applicable
