The PTS data set is used as temporary storage for SYSMODs. It contains one member for each SYSMOD received. Each member is called a modification control statement (MCS) entry and is an exact copy of the SYSMOD as it was received from the SMPPTFIN data set. The name of an MCS entry matches the ID of the SYSMOD it contains. Generally, the MCS entries are kept on the PTS until the SYSMOD is accepted; then, under normal processing, they are deleted.

Each PTS data set must be associated with only one global zone. The allocation of space and directory blocks for the SMPPTS depends on your plans for installing and maintaining the functions managed by the global zone. For more information about allocating the SMPPTS data set, see SMP/E for z/OS Reference.
