### ALP3801: Argument expected

When processing one of the EQU, IRP, IRPC, FOR, or FORC macro directives, the required argument immediately following the directive was missing or incorrectly specified.

Recovery: Modify the referenced token so that it is a valid argument for the directive. If this directive appears within a nested macro expansion, check to see that correct arguments were passed to outer level macros, or that outer level macro definitions are correct.
