End macro definition directive

    Format

      .ENDM  [macro-name]

1  –  Parameter

 macro-name

    The name of the macro whose definition is to be terminated. The
    macro name is optional; if specified, it must match the name
    defined in the matching .MACRO directive. The macro name should
    be specified so that the assembler can detect any improperly
    nested macro definitions.

2  –  Description

    .ENDM terminates the macro definition. See the description of
    .MACRO for an example that uses an .ENDM directive.

3  –  Notes

    o  If .ENDM is encountered outside a macro definition, the
       assembler displays an error message.
