Coding the JCL statements for disassembling control blocks in batch

The following figure shows a generic example of the JCL to disassemble control blocks in batch.

The example shows all of the statements Database Integrity uses during the disassembly process.

When disassembling a control block, the significant DD statement is the one that describes the DBD, PSB, ACB, or DFSMDA library containing the control block to disassemble. However, you do not have to specify this data set in the JCL. You can specify the data set name with a keyword on the GLBL or DECODE control statement instead.
