Q) How the online screen and respective cobol+IMSDB connections are established
1) where i could get this information?
2) And how the data is transfering from online screen to cob+DB pgm... where can i find this setup

Q) By seeing an existing COBoL+IMSDB pgm in source lib how to justify whether is BMP or MPP or DLI?

I've posted this diagram flow before - did you search the forum?

Here are a few hints...all IMS programs have a linkage section with the PCBs defined

An MPP has no JCL
A BMP has JCL but the databases are not defined in the JCL - they exist in the PSB

A DLI has JCL and the databases are there because they are "offline"
