SAVE
When editing a database, the SAVE command causes File-AID for IMS to immediately issue a DL/I checkpoint call. When editing a segment/layout XREF or a selection criteria file, SAVE causes the data to be stored back into the data set or member.
For a partitioned dataset member, the member is rewritten with the same name and the library statistics for the member are updated.
The SAVE command does not terminate the selection criteria edit session. You normally terminate selection criteria edit by entering the RETURN command. The RETURN command causes a SAVE to be issued before termination if any changes were made since the selection criteria file was last saved.
