As looking at CICS program we can look for EXEC CICS and can say that it is an online program. How to identify the program is IMS DC in similar way?

Look for the IMS API or any IMS specific keywords - PCB PSB etc.

Yes, but if it's IMS DC and not IMS DB, how would you tell?

the short road ... look at the application documentation to find out
the lonag and windy road ...
look at the IMS/DC manuals, and search the programs for the constructs needed to interface a terminal

All the IMS program have same structure. Like Procedure Division having USING with PCB names, I/O Area. Linkage will have PCBs as per the PSB used in program. Then what differentiate one with other type of program?

If the program is using IO-PCB it's an IMS DC program. Read about IO-PCBs more, please.
