Did you include the  standard file for the model PIC where RP0 and RP1 are
defined....?

>Actually there are comments before the code and a bunch of retlw between

the

>ERROR TSAIL.SRC 188 : bit number must bee from 0 to 7
>ERROR TSAIL.SRC 189 : bit number must bee from 0 to 7
>ERROR TSAIL.SRC 195 : bit number must bee from 0 to 7

>Where   "bcf STATUS, RP0                ;set to bank 0 " is line 188
>
>I did an assembly with the /D option and the symbol table listed :
>STATUS=0003, RP0=5003 & RP1=6003  so the symbols seem to be there, but
>contain more bits than needed.  The listing notes that subsets of a label
>include the primary label value.  So where RP0 is bit 5 of the STATUS
>register, it has a value of 5003.
