I had something similar happen when I ported from 16C74 to 12C509. I can't remember exactly what the problem was, but I do know I had something wrong which caused the fault you have - Either the ORG was wrong, the CBLOCK origin was wrong or the incorrect processor type defined/wrong .INC file included

If you have recompiled and the fault doesn't go away, have a look at your LST file and make sure your data and code start at the addresses you expect.

Regards,
Neil

Make sure that if you have edited your code, you must recompile it.
Even though it appears changed when you run the code it is using the
instructions which were last compiled.
Example:  If you had a goto CONFIG statement on the third line of
START which was then modified to remove the goto CONFIG, the
simulation software would still goto CONFIG.  Once the program is
recompiled it is now using the newly modified code.


Hope this helps
