Send or Receive Map or Not!

[Lynda850]

I am a novice at CICS programming...I am a little confused. I need to create a screen to display only data pulled from the history file. Since the key will be passed from various other screens (depending on which screen they choose to view the new History screen from), do I need a SEND and RECEIVE Map or just a Send Map?

Depends on your program spec. What does it say?

Hi William, thanks for responding. I was told to 1) capture when certain fields changed from other screens and write to a HISTORY file ✔️ then 2) Create a screen to display the history when wanted to view at a later time. A list of elements and those instructions are all I received.

Well, that sounds like two separate things. Firstly something to create your history, secondly something to allow the history to be viewed. At least two separate programs, and yes, you'll need to give the user functionality to do things, so sending and receiving for sure.

I have already modified various other programs to capture the changed data. What I need is a screen to display the history. Right now, the user enter a person's account number and have access to several screens, master data, fiscal data and a couple other screens just from that one entry. Being that this history screen is just displaying (no entry fields), do I need a Receive Map since there is nothing to receive entered from the screen? The account number will be passed in the Commarea.

If you just display a screen, what is the user going to do?

The screen will display historical changes for whatever account they entered at the main screen. For audit purposes they had me to capture the changes which I have already done by modifiying other already exisiting programs. Now they want a screen to display those historical changes since my users can't view the VSAM file.
