Abstract

A method is described which requires fewer keystrokes to reset an input-inhibited condition and to correct a keystroke error in the IBM PC Network SNA 3270 Emulation Program Product. The IBM PC Network SNA 3270 Emulation Program is a Program Product which emulates a 3274 Control Unit, 3278/3279 Display and 3287 Printer on the IBM Personal Computer (PC). On a real 3278 display, when an input-inhibited condition occurs, only the Reset key will reset the condition. However, many times input is inhibited because of a 3270 screen's field being full. In this case, the natural action for the operator to take is to press one of the cursor motion keys to move the cursor to a new field.

Keystroke Reduction of Input-Inhibited Condition Reset With Cursor Key and Enhanced Backspace Key

A method is described which requires fewer keystrokes to reset an input- inhibited condition and to correct a keystroke error in the IBM PC Network SNA 3270 Emulation Program Product. The IBM PC Network SNA 3270 Emulation Program is a Program Product which emulates a 3274 Control Unit, 3278/3279 Display and 3287 Printer on the IBM Personal Computer (PC). On a real 3278 display, when an input-inhibited condition occurs, only the Reset key will reset the condition. However, many times input is inhibited because of a 3270 screen's field being full. In this case, the natural action for the operator to take is to press one of the cursor motion keys to move the cursor to a new field. However, on the real 3278 display, this will not reset the input-inhibited condition, so after the operator has pressed the cursor motion key (which has no effect), the operator must press the Reset key and then press the cursor motion key to move to a new field on the screen. In the new method, when a cursor motion key (up, down, left, right, etc.) is pressed, if input is inhibited, the condition is reset. This allows the operator to move from a full field with one keystroke, instead of two or three keystrokes, as required on a 3278 display. On the real 3278 the backspace key moves the cursor to the left, one character. When an operator presses the backspace key, it is usually because the las...
