TEST—LISTDEB subcommand

Use the LISTDEB subcommand to list the contents of a data extent block (DEB). You must provide the address of the DEB.

If a copy of the control block is in extended virtual storage, the LISTDEB subcommand accepts addresses greater than 16 MB, even though the block itself will always be in virtual storage below 16 MB. Even if an absolute address has been specified, LISTDEB displays the virtual address before formatting the control block.

In addition to the 32 byte basic section of the DEB, you can receive up to 16 direct access device dependent sections of 16 bytes each, until the full length has been displayed. If you want, you can have only selected fields displayed.
