Use the VERCOUNT parameter to specify how many versions of a member to keep. The default value of zero, used in the example found in this chapter, indicates that all versions are kept. The number of versions specified using this parameter applies to all types that are versioned. The VERCOUNT parameter on the FLMATVER macro can be used to override this value for specific types.

Valid values are 0 and any integer value greater than or equal to 2. Because that is what is already in the hierarchy, 1 is not a valid value. If you specify a value other than the default and you intend to version multiple groups in the hierarchy, either use the FLMALTC macro to specify different VERPDS data sets for each group or use the @@FLMGRP variable in the VERPDS name on the FLMALTC macro. Failure to allocate and specify unique VERPDS data sets can result in difficulty retrieving versions.
