Abstract

PURPOSE:To enable to discriminate errors immediately after a file name was inputted in error by staring the retrieval to a file in parallel with key input. CONSTITUTION:A keyboard KB is provided with a file name input start key KB2 and file name input end key KB3, and a data inputted with a keyboard controller KBC is encoded. A refresh memory M is controlled with a CRT controller DPC and a character symbolic code is displayed on a CRT device DP. The processing step is read out from a control memory ROM with a controller MC1. Write/read of RAM are made with a controller MC2. A file information is stored in a magnetic disc MD. If the file name is inputted in error for the retrieval of the file information, it is informed by a buzzer B and back space is given on a CRT device DP automatically.
