SCOPE

This parameter allows the user to control the extent to which references are traced. Values for this parameter are described in the following:

*NOMAX—(default) No maximum level of expansion.
*NEXT—Expansion proceeds to the next level only.
*EXTFUN—This option is intended for use with objects of type FUN. Expansion proceeds up to and including the first external function on each chain of references. This enables the user to determine the functions referenced by a given program.
