#43497 - Is there a non-unique label directive? |
Is there a way to use non-unique labels in 8051 assembly? I checked the Metalink Asm51 manual and it doesn't look like it, but I didn't really understand some of the macro information.
Let me explain where I am coming from. I wrote a program in assembly for a class some time ago that was for the Motorola 68000. I recall that the assembler allowed special label directives - the labels did not have to be unique. I think the assembler would choose the closest generic label for branching instructions, something like this: 1$ <assembly commands...> CJNE A,#0,1$ 2$ <assembly commands...> CJNE A,#0,2$ 1$ <assembly commands...> CJNE A,#0,1$ The previous example would be effectively assembled as if it were like this: LABEL1: <assembly commands...> CJNE A,#0,LABEL1 LABEL2: <assembly commands...> CJNE A,#0,LABEL2 LABEL3: <assembly commands...> CJNE A,#0,LABEL3 The nice thing about it was that every label didn't have to be unique in the code. Can this be done for the 8051? Any input is appreciated. - Lee |
