Abstract

PURPOSE:To inform that a memory capacity is in a full state, by inhibiting the storage of a data such as correction, insertion, etc., exceeding the memory capacity and displaying a special symbol, when a computer is full of memory in an electronic desk computer for storing a formula or a program. CONSTITUTION:An electronic desk computer for storing a program is constituted of a central processing equipment 1, an ROM2, an RAM3, an input/output buffer 4, a key 5, a display buffer 6 and a display body 7, and the central processing equipment 1 reads a key in accordance with a process of the ROM2, and operates in accordance with a formula or a program which has been written in the RAM3. In this RAM3 are stored a formula and a program. If a key operation for correcting or inserting a formula or a program exceeding this memory capacity is executed, it is inhibited, and a specific symbol mark 8 is displayed every one second as a display of impossible insertion, by the display body, repeating to turn on and off.
