IRPC
The IRPC built-in macro is defined as follows:
IRPC parm-name, parm-string macro-body ENDM
Where
| parm-name | is the parameter name that is used in the macro-body. Each time the macro is expanded, subsequent characters from the parm-string are used to replace parm-name in the macro-body. |
| parm-string | is the text string whose characters are used to replace parm-name in the macro-body. |
| macro-body | is the text that is expanded when the macro is invoked. |
For example:
IRPC sendchar, TEST
MOV R0, #'sendchar'
CALL outchar
ENDM
expands as:
MOV R0, #'T'
CALL outchar
MOV R0, #'E'
CALL outchar
MOV R0, #'S'
CALL outchar
MOV R0, #'T'
CALL outchar
