AVD assigns a contiguous disk file to a virtual disk VDn:.
 
    The first available virtual disk unit will be used, and
        will be assigned to the first available logical VSn:,
        (e.g., ASN VD3:=VS:/LOGIN is effectively executed).

    The user must be privileged in order to create a virtual disk.

    Command format:

        >AVD filespec[/sw]

    where [/sw] is one of the following switches:
        /LI            List the status of virtual disks
        /BR            Breif listing of virtual disks%2N            
        /ID            Print the current version number and exit
        /HE[lp]        Print this help message and exit
        /NM            Suppress informational messages
        /VM            Assign VDn: to VM: (i.e., ASN VDn:=VM:)
        /RO            Define VDn: with READONLY access
        /CR:mmmm       Create VDn: with mmmm (decimal) disk blocks
