<p>PURPOSE:To greatly improve the operability of command input by easily selecting an input command to be redisplayed and a previously registered command which is high in frequency of use. CONSTITUTION:The screen of a display device 1-3 has a command input area and a command history area. In an input command storage area 1-11, several latest input commands are stored. In the previous registered command storage area 1-10, several previously registered commands frequently used are stored. A process decision means 1-6 discriminates whether input data from a keyboard 1-1 is a command to be executed or a cursor indication. A mutual relativity judging means 1-7 relates screen correspondence information to the input command. A command registering means 1-8 registers the previously registered commands. A user frequency discrimination means 1-9 discriminates the user frequencies of the previously registered commands.</p> |
