Wang 700 Basic Operation

The Wang 600 Advanced Programmable Calculator uses "Register Notation" to perform operations. This differs from most modern calculators which use Reverse-Polish Notation (RPN) or Algebraic Notation. All operations on the Wang 600 are perform either on the display or between the display and a register.

One of the more noticeable features of the calculator is the two display registers, "X" and "Y". The "X" display is the main display, where numbers are entered and (normally) recalled. The "Y" register is used as the target for arithmetic operations and as the register number for indirect operations. Both registers are also used as parameters for certain other functions, such as ploting output.

The main number-entry keypad is located right-center. It also include arithmetic operations using the "X" display targeting the "Y" display. In addition, square and square-root functions on the "X" display are located there.

Located left-center are keys for operations on the register (direct and indirect) functions and a few miscellaneous functions. Numbers are moved between the "X" and "Y" displays using the "↑" (copy X to Y), "↓" (copy Y to X), and "↑↓" (exchange X and Y) keys.

Located far-left are some scientific functions and special keys for printing.

Located far-right are programming functions keys, some I/O functions, and special program manipulation keys. Most important is the PRIME key, which is a general calulator reset function. This restores the calulator to a known state, clears the X and Y registers, but does not clear the general registers.

Above the main keyboard is a strip of keys labeled "00" through "15", with toggle switches to the left. The keys, in combination with toggle switches, can be used to produce any program or function code, including subroutine calls. The toggle switches are used to form the binary value for the upper nibble of the code. Flipping these switches does not produce any code or action. Pressing one of the "00" through "15" keys will produce the code, and associated action, based on the toggle switch settings (high nibble) and the key number (low nibble). For example, setting toggle switches "40" and "10" on and pressing "04" will produce the code 05 04.

Here is an example of performing the arithmetic operation "5 + 6".
