An authorized program can delete a subspace by invoking the IARSUBSP macro with the DELETE parameter and supplying the subspace STOKEN that the system returned when the program created the subspace. It is most efficient to delete all subspaces at once.

The program that deletes a subspace must be running under the same task as the program that created the subspace. The program will abnormally end if it attempts to delete a subspace that it, or any other program, is running in.

The system disassociates the storage from the subspace before deleting the subspace, if the program has not already done so.

Deleting a subspace does not remove its associated entry from the DU-AL. See Removing the subspace entry from the DU-AL for information about deleting the entry.
