PROPAGATE.SPACE = (NO|YES, NO|YES)

Edit online
PROPAGATE.SPACE will be new Initialization Parameter for controlling propagation of SPACE parameter
  • 1st sub-parameter- when the DATACLAS is propagated from the source dataset, this parameter determines whether to also propagate the SPACE attributes from the source dataset.
    • Value ‘NO’ means the SPACE attributes from the source dataset will not be propagated when the source dataset DATACLAS is propagated. It is a default and legacy behavior.
    • Value ‘YES’ means the SPACE attributes from the source dataset will be propagated even though the source dataset DATACLAS was propagated as well. If the DATACLAS used in allocation has OVERRIDE SPACE=YES, then the data class space attributes will override the space attributes from other sources (FROM Dataset space).
  • 2nd sub-parameter - when the DATACLAS is specified in the COPY TO section (legacy method), this parameter determines whether to also propagate the SPACE attributes from the source dataset.
    • Value ‘NO’ means the SPACE attributes from the source dataset will not be propagated when a DATACLAS is specified in the COPY TO section. It is a default and legacy behavior.
    • Value ‘YES’ means the SPACE attributes from the source dataset will be propagated even when a DATACLAS is specified in the COPY TO section. If the DATACLAS used in allocation has OVERRIDE SPACE=YES, then the data class space at-tributes will override the space attributes from other sources (Dataset space etc.).
Note: This parameter has no effect on the sending side. The sending side always sends the SPACE information. When specified on the receiving side, this parameter provides greater specificity in determining when the information is used in a new dataset allocation.
