I want to use "far" define a variable. I have added the file "L51_BANK.A51" into my project, and select the LX51 instead of BL51,and AX51 instead of A51. I modify the file "L51_BANK.A51" as following:
?B_NBANKS EQU 4 ?B_MODE EQU 1 ?B_RTX EQU 0 ?B_VAR_BANKING EQU 1
They'll be some sort of library stuff - search the knowledgebase for "?C?CLDOPTR"
You have an configuration error. See: http://www.keil.com/support/docs/2906.htm
