hi, I have a OBJ file from 3rd party, which has some CONSTs. The file name is tdc.obj , and the const are allocated by command BANK1(?CO?tdc) . However, after I change this file name to tdcw.obj , and banking the constant using BANK1(?CO?tdcw). it does not work . I wonder that could I change the OBJ file name? why I cannot change the name from tdc.obj to tdcw.obj and using ?CO?tdcw? Thank you very much.
