#94394 - Macros Responding to: ???'s previous message |
In my ASM programs I usually put the following macros:
; Macros: JPLESS MACRO R,DAT,LAB ; Jump to LABEL if REG less than DAT CJNE R,DAT,$+3 JC LAB ENDM JPGTEQ MACRO R,DAT,LAB ; Jump to LABEL if REG greater-equal to DAT CJNE R,DAT,$+3 JNC LAB ENDM Note: R can be any register or accumulator - just that CJNE is a legal command, DAT can be only "immediate" - #N in case of registers, but also any of direct RAM if R is accumulator. If accumulator is to be compared with a register, than the register only can be taken as a direct address, eg. 0 - 7. Examples:
JPLESS A,ADDR38H,LABEL1
JPGTEQ @R0,#0AEH,LABEL2
JPLESS A,3,LABEL3 ; Compare A with R3, bank 0
