Miscellaneous Directives5.6 Miscellaneous DirectivesThis section discusses miscellaneous directives. The .end directive terminates assembly. It should be the last source statementof a program. This directive has the same effect as an end-of-file character. The .listoff directive overrides the –l option and prohibits source listing. The .liston directive begins source listing. The .mmregs directive defines symbolic names for the memory-mappedregister. Using .mmregs is the same as executing a .set for all memorymappedregisters—for example, greg .set 4—and makes it unnecessaryto define these symbols. See Table 5–2, page 5-25, for a list of memorymappedregisters. The .set directive equates meaningful symbol names to constant valuesor strings. The symbol is stored in the symbol table and cannot beredefined; for example:bval .set 0100h.byte bvalB bval5-10
Directives Reference5.7 Directives ReferenceThe remainder of this chapter is a reference. Generally, the directives areorganized alphabetically, one directive per page; however, related directives(such as .if/.else/.endif) are presented on the same page.
