Jon:

It's probably file register 0, the INDF register.  In
Microchip syntax, the code fragment you posted would look like
this:

    INDF    EQU     0

    ....

    no_zs:

            MOVWF   INDF    ;Personally, I'd rewrite these
            MOVLW   ASC_0   ;three lines as:
            ADDWF   INDF    ;
                            ;    ADDLW   ASC_0
                            ;    MOVWF   INDF
