 		 #9301 - RE: use of multiply in large data arrays
Patrick,

This may be faster and more concise:
get_array:
;input r1 = member number (0,)
;input r0 = member byte (0,)
mov a,r1 ;1;12;
mov b,#MEMBER_LENGTH ;3;24;
mul ab ;1;48;
xch a,b ;2;12;
add a,#LOW(ARRAY_ADDRESS) ;2;12;
xch a,b ;2;12;
addc a,#HIGH(ARRAY_ADDRESS) ;2;12;
mov dph,a ;2;12;
mov dpl,b ;3;24;
mov a,r0 ;1;12
movc a,@a+dptr ;1;24
ret ;1;24
