File Status Inquiry  Access File Status Codes using CICS http://www.simotime.com

Introduction
(Next) (Previous) (Table-of-Contents)

This example uses a a suite of COBOL programs and BMS mapsets to display a screen to prompt a user for a file status code. When the user enters the code a brief discription of what caused the condition will be displayed. The programs use command level CICS statements to access the VSAM File with status codes and descriptions. The information is displayed to a 3270 terminal or terminal emulator. The programs run on an IBM Mainframe System with CICS or a Microsoft Windows System with Micro Focus Server for Mainframe Migration.

Display of Return Codes

To display the File Status screen a COBOL program and a BMS screen is used. The File Status Screen contains a prompt for a new File Status Code and the file status information from a previous request.

 FILERC1              Data Base Management System                 2007/11/11
 STOA              File Status Codes - Inquiry Option            20:30:00:00

   Next File Status Code: 35__                (or extended hex value): __


     Code      Description




                PF3-Menu                                            PF12=Esc

Once a new File Status Code is entered the Repository of File Status Codes is accessed and the new status information is displayed.

   Next File Status Code: 0035                (or extended hex value): __

Various EXEC CICS commands are used to access the repository of file status codes and re-display the screen.

Repository of File Return Codes
(Next) (Previous) (Table-of-Contents)

The Repository of File Status Codes is a VSAM, Key Sequenced Data Structure (or KSDS). It has a record length of 80 bytes with a 4 byte key starting in position 1 of the record. The following copy file shows the record structure.
