Hi,

Try this (untested):

        cblock
                d1
                d2
                d3
                d4
                d5
                d6
                d7
                d8
                d9
                d10
                tmp
                i
        endc

bubble:
        movlw   9
        movwf   i
        addlw   d1
        movwf   FSR

loop1   movf    INDF,w  ;for i = 9 to 1 'd10 to d2
        movwf   tmp     ;tmp = d[d1+i]

loop2   decf    FSR,f   ;for FSR = (d1+i-1) to d1

        movf    tmp1,w  ;compare
        subwf   INDF,w
        skpc            ;change this to skpnc to change sort order
         goto   noswap

swap    movf    tmp1,w
        xorwf   INDF,f
        xorwf   INDF,w
        xorwf   INDF,f
        movwf   tmp

noswap  movlw   d1
        xorwf   FSR,w
        skpz
         goto   loop2

        movlw   d1
        addwf   i,w
        movwf   FSR
        movf    tmp,w
        movwf   INDF    ;d[d1+i] = tmp
        decf    FSR,f
        decfsz  i,w
         goto   loop1

        return

;equivalent in C

        for (i=10;i>1;i--) {
           tmp=d[i];
           for (k=i-1;i>0;k--)
               if (d[k]>tmp) {
                  tmp2=tmp;
                  tmp=d[k];
                  d[k]=tmp2;
               }
           d[i]=tmp;
        }
