VSSAVE
Specifies if when operating upon a VSAM shared file, during a CHANGE command with the ALL operand, a SAVE is issued before commencing the CHANGE.
NO
Z Data Tools does not issue a SAVE before commenting the CHANGE.
YES
Z Data Tools issues a SAVE command which ensures that any updates made to the file so far are saved. During the CHANGE ALL process, when using VSCHGAUTO (and a VSCHGFRQ value), the change process may need to refresh records as it goes (due to concurrent updates by other users). That refresh may discard other updates that had been made in this edit session to records on the file. Leaving the setting at YES, to issue a SAVE before the CHANGE commences, is therefore recommended as it will ensure the state of the records that have been updated.
