Local labels when porting 68HC11 code to HCS12

micmed — Fri, 13 Feb 2026 14:09:53 GMT

Hello,

I have some ancient 68HC11 code that used the x68c11 assembler (by AvoCet/2500AD?) that I am supposed to be migrating to something not end of life. I settled on the MC9S12A32CFUE and have set up an environment using CodeWarrior 5.2 with a modification to support this derivative (refer to: thread 585450).

This old code makes use of "dollar local labels" very often, and I have not been able to find an equivalent replacement that is accepted by the CW5.2 assembler. My question is, does this feature exist in the CW5.2 assembler, and if not, is there an equivalent implementation?

Example of syntax:

MAIN

NOP

BRA 1$

NOP

These labels get reused throughout the .S file

Thank you.

Hello @micmed,

I'm afraid the assembler does not support local labels.

Refer to Assembler_HC12.pdf

\Freescale\CWS12v5.2\Help\pdf\

You can replace it with standard labels.

Regards,

Daniel
