pidadr

    OpenVMS usage:process_id
    type:         longword (unsigned)
    access:       modify
    mechanism:    by reference
    Process identification (PID) of the process to be resumed. The
    pidadr argument is the address of a longword containing the PID.
    The pidadr argument can refer to a process running on the local
    node or a process running on another node in the cluster.

    You must specify the pidadr argument to delete processes in other
    UIC groups.

 prcnam

    OpenVMS usage:process_name
    type:         character-coded text string
    access:       read only
    mechanism:    by descriptor-fixed-length string descriptor
    Name of the process to be resumed. The prcnam argument is the
    address of a character string descriptor pointing to the process
    name.

    A process running on the local node can be identified with a 1-
    to 15-character string. To identify a process on a particular
    node on a cluster, specify the full process name, which includes
    the node name as well as the process name. The full process name
    can contain up to 23 characters.

    You can use the prcnam argument to resume only processes in the
    same UIC group as the calling process, because process names
    are unique to UIC groups, and the operating system uses the UIC
    group number of the calling process to interpret the process
    name specified by the prcnam argument. You must use the pidadr
    argument to delete processes in other UIC groups.
