The known version numbers returned by Atoms and Systems are anomolous:
       Machine Version
        &0002, &3450 - Atom Econet 3.50
        &0003, &3450 - System 3/4 Econet 3.50
        &0004, &344F - System 5 Econet 3.40

These can be dealt with in printout by using code similar to:
    DEFFNver(A%)
    =LEFT$(FNh0(A%,4+((A%AND&F000)=0)),1)+"."+FNh0(A%,2)
