Title: Data exchanging device for simple software
Inventor: OBA RYOICHI
IPC: G06F9/06
Filed: 1985-05-10
Abstract: PURPOSE:To improve operability when data are exchanged by providing a processor which accepts a data operating instruction and stores the information in a memory device separately from each simple software and therefore attaining an integrated operation. CONSTITUTION:The memory device M1 stores an exchange data file between simple softwares AP1 and AP2. The AP2 writes the exchange data to the device M1 with a data output instruction while the AP1 reads the exchange data out of the device M1 with a data input instruction. A processor PU1 accepts an indication for data exchange via an integrated user interface based on a production program for information on the data exchange stored previously and produces the files of data exchange information to be delivered to each simple software to store them in memory devices M2 and M3. While both AP1 and AP2 use the files stored in the devices M2 and M3 to perform the data processing. Thus an integrated operation is possible through the same user interface with the use of the processor PU1. This improves the operability when data are exchanged.
