HI-TECH C Assembly Language
In this example, if ABC is non-zero, the first jmp instruction will be assembled but not the second or
third. If ABC is zero and DEF is non-zero, the second jmp will be assembled but the first and third
will not. If both ABC and DEF are zero, the third jmp will be assembled. Conditional assembly
blocks may be nested.
4.3.8.20 MACRO and ENDM
These directives provide for the definition of macros. The MACRO directive should be preceded by
the macro name and optionally followed by a comma-separated list of formal parameters. When the
macro is used, the macro name should be used in the same manner as a machine opcode, followed
by a list of arguments to be substituted for the formal parameters.
When used, this macro will expand to the 2 instructions in the body of the macro, with the formal
parameters substituted by the arguments. Thus:
expands to:
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.

For example:
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
