 pidadr

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

    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
    Process name of the process to be deleted. The prcnam is the
    address of a character string descriptor pointing to the
    process name string. 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 use the prcnam argument to delete 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
    groups.
