IPC: G06F3/02
Filed: 1986-10-01
Abstract: PURPOSE:To contrive to decrease the changing-over operation of a character type by character-converting the attribute of a character string to be inputted as the attribute of the inputted character string at the position near the input position of the already inputted character string. CONSTITUTION:When a character key input exists, and an automatic shifting changing- over flag is on, an automatic character type flag is referred to, and when the flag is off, a manual character type flag is referred to and a key code is converted to a character code in accordance with the type code set in the flag. After the input position is moved, the automatic shifting changing-over flag is decided, and when the flag is on, the inputted character type of an input position is decided. When the inputted character is not present, the character type closest to the input position is investigated and the obtained character type is set to the automatic character type flag. When the character after the input is not the character type expected by a user by the automatic shifting changing-over, by providing a means to pushing down simultaneously a control key and a shifting key and change the inputted character type immediately before it, an error input can be corrected. Thus, at the time of correcting the inputted character string, the character type changing-over operation can be omitted and the operability is improved.
