A n

Add the number in storage location n into the accumulator.

S n

Subtract the number in storage location n into the accumulator.

H n

Transfer the number in storage location n into the multiplier register.

V n

Multiply the number in storage location n by the number in the multiplier register and add into the accumulator.

N n

Multiply the number in storage location n by the number in the multiplier register and subtract from the accumulator.

T n

Transfer the contents of the accumulator to storage location n and clear the accumulator.

U n

Transfer the contents of the accumulator to storage location n and do not clear the accumulator.

C n

Collate the number in storage location n with the number in the multiplier register, i.e. add a "1" into the accumulator in digital positions where both numbers have a "1", and a "0" in other digital positions.

R 2 to the power (n-2)

Shift the number in the accumulator n places to the right; i.e. multiply it by 2 to the power -n.

L 2 to the power (n-2)

Shift the number in the accumulator n places to the left; i.e. multiply it by 2 to the power n.

E n

If the number in the accumulator is greater than or equal to zero execute next the order which stands in storage location n; otherwise proceed serially.

G n

If the number in the accumulator is less than zero execute next the order which stands in storage location n; otherwise proceed serially.

I n

Read the next row of holes on the tape and place the resulting 5 digits in the least significant places of storage location n.

O n

Print the character now set up on the teleprinter and set up on the teleprinter the character represented by the five most significant digits in storage location n.

F n

Place the five digits which represent the character next to be printed by the teleprinter in the five most significant places of storage location n.

X

Round off the number in the accumulator to 16 binary digits.

Y

Round off the number in the accumulator to 34 binary digits.

Z

Stop the machine and ring the warning bell
