Re: Passing an address to a #define in C

[GusSabina <gussabina at yahoo dot com>]

Hello Andi:
Thanks for the post.

I'm aware of the Labels as a Value feature. However, it seems it only work
with goto label instruction.
In my particular case, I need to use the label just to pass the relative
address of the label as a parameter to a @define statement. 
I tried using this and it didn't work.

Any other idea?

Thanks
Gus
