Not a problem.

You might want to edit your profile and change or delete your "signature" which is currently

Unlike CICS, when you compile your IMS program, it does not generate the screen. Sit down with an 80 X 80 screen design format and design the screen. Take into consideration the invisable attribute bytes. Then code your MFS block. Take that MFS block and code "modified" fields in working storage in your program. Make sure they match. Linking takes place thru your transaction and subsequently the gens needed - TRAN, PSB and ACB. This is something that your DBA can help you with. When your transaction is invoked, it invokes your program which you will use to put up any screens associated with your process.

-- Create Online PSB for your online program,
-- In the Online IMS region Define Transaction Id and relate PSB and program, also ACBGEN - This is done by IMS Admin folks.
-- In the MFS - put your transaction code - This will invoke your transaction

Still i could not understand.

see...
1. first i design the the MFS by using DIF/DOF and MID and MOD.
2. Then i compiled the MFS.
3. The preogram is also created.
4. Here my question is how will i see the online screen and how will link the program to MFS.

Please somebody explain detail. Otherwise please send some link.
I know the concept but geting problem while implementing i mean MFS is ready and program is ready.....then what need to do?????

Hi,
Go to the IMS message region , follow the below sequence
1. Start your program
command: /sta [pgmname]
2. Start your transaction
command: /sta [tranname]
3. Start your MFS
command: /for [mod name]

Now you can see your screen in the message region
but make sure that you already created PSB and ACB gens

This is a difficult concept to grasp. It's like which comes first, the chicken or the egg?

The transaction that is defined (hopefully by your DBA) invokes the process. The transaction is coded in your MFS.

When you enter the command /for modname, the screen which you developed will be appearing on the screen...once you enter the data or you hit a key, the transaction code which you mentioned in the MFS will automatically invokes your program (as the DBA defines the program name for this transaction code, so you have to use the same program name while using this transaction code), so as written in the program for the entered key,the screen will behave.

Thnx to all...:-)

Can anyone tell how to compile the MFS.
I mean the steps from starting to end for designing an online screen.
Actually i never involved for designing of online screen. But know the concept of IMS DB/DC.

Hello,

Your best source for this type of info is in your organization. People there can tell you exactly what steps are to be used on your system.

People here may post general direction, but the people at your site will know exactly how things are to be done there. Each person working with IMS should not seek out their "own way", but should use the common practices already established.

Hello Sanjib,

When this

Hi Sanjib,

You can follow the below steps for the coding and invoking the online program,

1. MFS GEN (By you)
2. DBD GEN (by your DBA)
3. PSB GEN (By you)
4. ACB GEN (By your IMS Admin)
5. Compile your program with the proper online PSB.

Now you can invoke your program with proper transaction ID and test it.

These are all the major steps you need to be followed to create an online program.

Hope it helps you.

Regards,
Suthagar. S
