0010 401000 Put X into 1000 (Sets 1001 - 1004 to zero)
0011 001000 Load accumulator with X
0012 250048 If X is zero jump to halt instruction
0013 240017 If X is negative, skip next 3 instructions
0014 001501 Load +1
0015 031502 Store at S (sign)
0016 260022 Branch unconditionally around next 5
0017 001503 Load -1
0018 031502 Store at S
0019 001500 Load zero
0020 021000 Subtract X (This makes a negative X positive)
0021 031000 Store back at X
0022 001501 Load 1

0030 001000 Load X
0031 2370000 Shift left by I (Contents of register 2)
0032 360008 Shift right 8 (This isolates an octal digit)
0033 011001 Add previous Y
0034 031001 Store back at Y
0035 000002 Load I
0036 011501 Add 1
0037 030002 Store at I
