Using DFSMShsm commands

Before using the DFSMShsm commands and their parameters, you should read and understand the following use and notational conventions for DFSMShsm commands.

A command consists of a command name usually followed by one or more operands. The maximum size of a DFSMShsm command and its operands is 1024 bytes. All operands described in this book are called parameters, which qualify certain commands to perform the requested functions.

Example: The parameters associated with the BACKDS command specify the name of the data set that you want DFSMShsm to back up and, optionally, the volume and unit that contains the data set to be backed up. An example of the BACKDS command is:

   BACKDS TEST.CASES VOLUME(VOL123) UNIT(3390) /*comment*/

where:

BACKDS: is the command name.
TEST.CASES: is the name of the data set you want to back up.
VOLUME(VOL123): is the parameter, specifying the volume that contains the uncataloged data set to be backed up.
UNIT(3390): is the parameter, specifying the unit where the volume can be allocated.
/*comment*/: is a comment about the command, the parameter, or both.

All TSO conventions apply to the syntax of DFSMShsm commands. DFSMShsm commands use positional and keyword parameters.
