Arithmetic Formats in an Information Processing System

This article discloses an interface which allows the operator to select the format of the number displayed as the arithmetic total in an information processing system.

The operator may initiate the arithmetic mode by pressing either the Add (+) key, the Subtract (-) key, the Constant (CONST) key, or the Arithmetic Request (ARITH REQST) key. If the Add or the Subtract key is initially pressed, then either of these keys acts to insert the (+/-) value of the cursored number into the "Total" as the initial value. When the arithmetic mode is initiated, the Context field of the First Status Line will display "Arithmetic". The prompt line will display: "Total = nnn.nn", where nnn.nn is the value of the cursored number when the Add key is pressed or the negative of the cursored number when the Subtract key is pressed.

If the Constant key is initially pressed to invoke the Arithmetic mode, then the Context field of the first status line will display "Arithmetic", but the prompt line will display the following to allow the operator to type in the desired constant: "Constant = ".

If the CONST key or the ARITH REQST key is pressed to initiate Arithmetic, then the initial value of the Total is zero.

The format of the Total that is displayed on the prompt line will be based on the active Arithmetic format. In other words, the decimal point, thousands- position separator, and the number of decimal places to the right of the...
