The V00 is the version. I have seen it used once for a conversion. The regular production system kept creating the V00 version while they were testing the new jobs that created the V01 version. When the new jobs went into production replacing the old jobs, they went in creating the V00 version.
That was the explanation I received when I questioned the programmer when I saw the V01 on the tapes that I was responsible for. Thank you and have a Terrific day!
