Personal Computing Device for Editing Mainframe Data

摘要

A personal computer executes a productivity application that communicates with a mainframe computer via a communications network. The productivity application configures the personal computer to retrieve datasets formatted according to a format associated with the mainframe and convert the data in the datasets to a second format native to the productivity application. While in the second format, a user may modify the data. If so, the productivity application configures the personal computer to convert the data back to the first format, update control fields in the data set, and send the modified dataset back to the mainframe.

主权项

1. A method implemented by a processing circuit of a personal computing device, the method comprising:
retrieving a Virtual Storage Access Method (VSAM) data block from a mainframe computer via a communications network, wherein the VSAM data block comprises a data record and a control field; generating an editable object from the data record based on control information in the control field, wherein the editable object is modifiable by a productivity application executing on the personal computing device; determining whether the editable object was modified by the productivity application; and if the editable object was modified by the productivity application, generating an updated VSAM data block comprising:
updating the data record to comprise modifications made to the editable object; andupdating the control field based on the modifications made to the editable object; and sending the updated VSAM data block to the mainframe computer via the communications network.
