This control enables/disables complex relocation(see Section 2.3.4). In most cases, the user isn't concerned about this control. However, in programs in which it is known that there are no complex expressions, it is useful for error-checking purposes to use NOCOMPLEXREL. It is the unusual program that requires complex expressions. The default is COMPLEXREL. The class is general.
Note: Complex relocation is any relocation expression, other than rterm + constant, rterm - constant, or rterm - rterm where rterm is relocatable. For example, rterm * 2 is complex.
