Abstract
PURPOSE: To improve an operational efficiency and a processing efficiency by making the error display for accumulation to a specific value in a stack memory and that for oveflow of operation different from each other in a minicomputer.
CONSTITUTION: The control is so performed that it may be decided whether the operation indicated by the key, which was operated precedently, can be executed or not each time function key 40 indicating a prescribed operation is operated; and if it is decided that the operation cannot be executed,numeric data, which was inputted prior to the current key operation, may be temporarily saved in stack memory 19. When numeric data is saved in the stack memory, it is decided by 15 whether the number of data stored in the stack memory reaches a specific value or not; and if it reaches the specific value, the error is displayed on 33 in the mode which is different from the error display mode for overflow of operation
