It is recommended that you maintain a list of available versions via the MV request type. Within the MV return is a space-delimited list of available versions. For example: 200 21T 21W 22T 23T 24T 25T 26T 27T 28T 29T 30T 31T 32T 33T 34T
NOTE: The PC*MILER-AS/400 Multi-Version Switch PC mileage server is designed such that if the mileage server (as400.exe) loses connection to a particular version of PC*MILER, the affected version will be removed from the list.
