The NACT transaction

The NACT sample transaction is used in the book Designing and Programming CICS® Applications, published by O'Reilly & Associates, Inc; ISBN 1-56592-676-5, to demonstrate the design and development of CICS applications. It is a COBOL pseudoconversational 3270-based CICS application that operates on the customer account file of a fictitious company, KanDoIT.

The NACT application provides the following services:

The logic of the application is divided into the following pseudoconversational steps:

  1. A menu is displayed to allow selection of the service required.
  2. The updated menu screen is read; the requested record is obtained and displayed
  3. If the record is modified, the changes are received and the file updated; the menu is re-displayed.

The Link3270 sample client programs request the record number for customer name JACOB JONES; retrieve the record and display, or store, the retrieved record.
