Macro-calls
The defined macro-name can be called from any location in the program by using the following format:
[<Label>]_<Macro-name>_ [<Actual-argument>, ...]
The MACRO can be called by using the macro-name.
When arguments are required, write actual arguments corresponding to the dummy arguments used in the
macro-definition. Multiple actual arguments must be separated by commas (,).
Actual and dummy arguments correspond sequentially from left to right. If the number of actual argu-
ments is greater than the number of dummy arguments, the excess actual arguments are ignored. If the
number of actual arguments is less than the number of dummy arguments, the excess dummy arguments
are replaced by nulls (00H).
Any label can be written before the macro-name.
Example:
Source file
ORG 0200H
CTAS EQU 00H
CTAE EQU 02H
CAFSET EQU 0101B
CAFRST EQU 0000B
CTBS EQU 10H
CTBE EQU 08H
CBFSET EQU 0001B
CBFRST EQU 0100B
