I've been trying to compile someone elses code using the MPASM assembler v2.01 (Windows).  It has worked for them, but not me :(

I get the following error message:

Error[115] PIC03V10.ASM 79 : Duplicate label ("PK_ADDR" or redefining symbol that cannot be redefined)

It seems to be complaining about:
PK_ADDR         equ     RxBuf+0
PK_LEN          equ     RxBuf+1
PK_CMD          equ     RxBuf+2
PK_DATA1        equ     RxBuf+3
PK_DATA2        equ     RxBuf+4
PK_CHK          equ     RxBuf+5

RxBuf is being used as a 6byte buffer for serial input, previously defined with RxBuf res 6.  PK_ADDR is the first byte (file register) within the buffer, PK_LEN is the second etc.  If this method isn't allowed by MPASM, how do I directly access the individual bytes within the buffer ?

I've read that MPASM has become more stringent in its error checking, but I haven't found any reference to the error 115.
Any ideas ?
