Compaction of inline data

The RECEIVE command automatically compacts inline data within SYSMODs when copying members to an SMPPTS data set whenever the COMPACT subentry in the active OPTIONS entry indicates compaction is to be performed (this is the default) and the driving system supports compression and expansion services. Otherwise, the RECEIVE command does not compact SMPPTS members.

When SMPPTS members are compacted, the modification control statements, inline JCLIN data, and inline ZAP data remain in their original, uncompacted state. All other inline data associated with each of the following modification control statements are compacted before being written to the SMPPTS data set member:
  • All data elements
  • All hierarchical file system elements
  • ++MAC
  • ++MACUPD
  • ++MOD
  • ++SRC
  • ++SRCUPD
