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;
}
