Macro Assembler
and passed as a decimal number, rather than as a string. This is useful if evaluation of the argument
inside the macro body would yield a different result.
By default, the assembly list file will show macro in an unexpanded format, i.e. as the macro was
invoked. Expansion of the macro in the listing file can be shown by using the EXPAND assembler
control, see Section 4.3.9.2,
4.3.8.21 LOCAL
The LOCAL directive allows unique labels to be defined for each expansion of a given macro. Any
symbols listed after the LOCAL directive will have a unique assembler generated symbol substituted
for them when the macro is expanded. For example:
when expanded will include a unique assembler generated label in place of more. For example:
expands to:
if invoked a second time, the label more would expand to ??0002.
If an argument is preceded by a percent sign %, that argument will be evaluated as an expression
The nul operator may be used within a macro to test a macro argument, for example:
IF nul
ELSE
ENDIF
down MACRO count
ENDM
down foobar
??0001 decfsz foobar
LOCAL more
more: decfsz count
goto more
...
...
goto ??0001
