Thanks, I place space between @ _config and that cleared up the warning [205] but the critical error [118] remains.

Error [118] c:\PBP\Buttoncmd.asm 94: overwriting prvious address contects (2007)

Apparently writing via _config directive doesn't override existing code at 2007h address. I have tried in vain to comment out existing config settings in .inc file but that also seems to not to help.

Any further help appreciated ... any other way to change configuration bit settings via MPLAB IDE v8.46 ...

Thanks for any help
