Abstract

PURPOSE: To make it possible to correct preceding input data even after a function key is operated, by providing a memory to save temporarily function data and numeric data.
CONSTITUTION: When a CE key is operated when function data memory digit ZF of Z register of RAM 12 becomes "1" after the first entry is completed, contents of the memory in stack RAM 19 indicated by stack pointer SP of RAM 12 are read out after clearing contents of ZF and are set to Z register. Therefore, displayed data is changed to preceding entry data. Newest entry data is erased by the first CE key operation; and when the CE key operation is further performed, data including fuction data is erased successively, and preceding data is displayed.
