Hi All,

i am not very familiar with CICS.I have got a requirement like i need to
find a flow for a online cisc program.I mean after giving the transaction
id i am going to a mainscreen.There its need some data to validate but
after entering some dummy data i am not able to forward to next screen.
I have analyse the driver source program as well but not getting the

Don't you have some trace tools like XPEDIT or trace master?
If it is available,set break points in the program and trace them by giving inputs which will help you understanding the flow.

Hi,
Actuallly there is a error in my previous post.I need to find the
flow for the whole system instead of program.Though the program
i have seen is the driver program.And its xctl`ed to another program
which is a exit program and link to a program which is a error handling
routine.I am not able to proceed further.
I need some ideas??how to find the flow for a system/application?

Review the system or application documentation. Other than manual inspection of the code, there's nothing stored in an online system like CICS that would tell you the program flow.

In COBOL-CICS, there are a few commands that will pass control from one program to another one:
  • CALL <pgm>
  • EXEC CICS XCTL PROGRAM(<pgm>)
  • EXEC CICS LINK PROGRAM(<pgm>)
  • EXEC CICS START TRANSID(<trans>)
  • EXEC CICS RETURN TRANSID(<trans>)
You have to play detective and follow these commands...

Use the CICS supplied debugging facility CEDF followed by the transaction name.

Do a CEDF, find the driver program name, and when u get a screen (analyse the driver program and find the valid value that can be inputed) and then input and u can get the flow from that.

What about a CICS auxiliary trace ?

Do you see a DFHAUXT DD statement in the start up JCL ?
