Title: Error preventing method for input of data
Inventor: SHIBUYA HIROHISA
IPC: G06F3/02
Filed: 1988-01-16
Abstract: PURPOSE:To avoid the data input errors on a routine input screen by supplying the check bits on the printed matters for each frame and comparing these check bits with those produced by the input of data. CONSTITUTION:The check bytes Z1 and Z2 are shown by an equation I when the weighting is applied at a position where the input screen data on a display 10 exists. Each digit of the input data is shown by an equation II. When data are supplied to the display 10 with operation of a keyboard, the check bytes are produced by the equations I and II. Then a screen check bit is supplied with operation of the keyboard every time the input of data is through with a single screen and a collating instruction is produced. Thus the produced check byte is compared with the input check byte. Then a normal input message is displayed when the coincidence is secured from said comparison. If the input of data is wrong, the line address or the column address of the equation II is varied and therefore the produced check byte is different from the input one. Thus a message showing an input error is displayed.
