HI-TECH C Assembly Language

A point to note in the above example: the & character is used to permit the concatenation of macro
parameters with other text, but is removed in the actual expansion.
storage) by opening the comment with a double semicolon, ;;.
comma (or other delimiter such as a space) in an argument then angle brackets < and > may be used
to quote the argument. In addition the exclamation mark, ! may be used to quote a single character.
The character immediately following the exclamation mark will be passed into the macro argument
even if it is normally a comment indicator.
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,
4.3.8.20 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:
100
A comment may be suppressed within the expansion of a macro (thus saving space in the macro
When invoking a macro, the argument list must be comma-separated. If it is desired to include a
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
