I am converting an 68HC11F1 program written in assembler to
MC9S12XEP100 using the free Code Warrior version 5.7.0. I want to use
conditional assembly to maintain HC11 and 9S12 code in same file.
I get many errors.
I then created a new assembler project and modified the default
assembler file main.asm as attached.
I defined line 30:
VERSION_A: EQU 0
and lines 48-50:
IFEQ VERSION_A
STD FiboRes ; store result
ENDIF
I get error A12202 not a hc12 instruction or directive.
I think the VERSION _A label and IFDEF and ENDIF directives are proper.
Why am I getting this error? What am I doing wrong?
Thanks,
Steve Buckser

Use just "IF VERSION_A==0"

The problem was my error and has been fixed. The IFEQ and ENDIF were
placed to starting in the leftmost column of their text lines.
Everything works when an additional space is inserted in column "0"
and they conditional directives start in column "1".
Thanks for your help.
