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
