SET_FVERS #channel [,version] or
SET_FVERS \file [,version]
The command SET_FVERS sets the version number of a file - versions higher than 65535 or smaller than 0 are regarded as version MOD 65536, version=0 (or if version is omitted) means that the version number will not be updated when the channel to that file is closed. This command supports the current default data directory (see DATAD$).
