PORTABLE TERMINAL EQUIPMENT CAPABLE OF EDITING MEMORY DATA, AND RECORDING MEDIUM WITH MEMORY DATA EDITING PROGRAM STORED

PROBLEM TO BE SOLVED: To provide portable terminal equipment, capable of preventing memory data whose edition is not completed from being erased and a recording medium for recording a memory data editing program. SOLUTION: In portable terminal equipment 10, when interruption, such as by an incoming, is generated at the time of editing memory data such as schedule by the operation of an operation part 18, a storage part 20 retains the interrupted area, while retaining a memory data area 20a. Then, when the interruption is completed, the memory edition is resumed by referring to the memory data area 20a, and the memory data whose edition is completed are preserved in a preserving part 26 and are read, when the schedule or the like is confirmed. Therefore, even if an interruption is operated during the memory data editing, the memory data whose edition is not completed can be prevented from being erased. Thus, it is not necessary to retry the memory data edition from the beginning, and it is possible to improve the usability of the memory data edition.
