Dear all, When I was compiling the PICDEM 2+ sample code for PIC18F452, I get the following error message. It look like MPLAB 6.40 is unable to regonize CLRW as a mnemonic. Warning[207] D:\PROJECTS\PIC+\DEMO18\P18MATH.ASM 101 : Found label after column 1. (CLRW) Warning[207] D:\PROJECTS\PIC+\DEMO18\P18MATH.ASM 111 : Found label after column 1. (CLRW) Error[116] D:\PROJECTS\PIC+\DEMO18\P18MATH.ASM 111 : Address label duplicated or different in second pass (CLRW) Have anyone having the same compile problem in MPLAB v6.40? Thanks & regards.
