You can use direct Indexed addressing mode to access the lookup table.

In assembly...

segment 'rom'

.table DC.B $10, $20, $40, $80

.reset

ld X, #0

ld A, (table,X) ; A now contains $10

inc X

ld A, (table,X) ; A now contains $20

In C (Cosmic):

const unsigned char table[] = {

1,2,3,4,5,6,7,8,9

};

void main()

{

unsigned char a;

a = table[0]; // a contains 1

}
