Debugging IMS batch programs in batch mode

You can use z/OS® Debugger to debug IMS programs in batch mode. The debug commands must be predefined and included in one of the z/OS Debugger commands files, or in a command string. The command string can be specified as a parameter either in the TEST run-time option, or when CALL CEETEST or __ctest is used. Although batch mode consumes fewer resources, you must know beforehand exactly which debug commands you are going to issue. When you run BTS as a batch job, the batch mode of z/OS Debugger is the only mode available for use.

For example, you can allocate a data set, userid.CODE.BTSINPUT with individual members of test input data for IMS transactions under BTS.
