Task: Cancel existing queued DFSMShsm requests.

The HCANCEL command is designed for the TSO user who wants to cancel a data movement request. The command cannot be used on a request that is already being processed.

To use the HCANCEL command, your user ID must be DFSMShsm-authorized or be the same as that of the command to be canceled. Identification of the command to cancel can be specified by the DFSMShsm request number, user ID, or data set name. A request number implies that only one request be found, but a user ID or data set name causes all existing nonprocessing requests that have the same user ID or data set name to be canceled.

You can determine the request numbers that you have active by using the HQUERY command with the REQUEST parameter. Two commands cannot be canceled: HCANCEL and HQUERY.

If no parameters are included in this command, no function results.

Abbreviation: The minimum abbreviation for the HCANCEL command is HCAN.
