 process-name

    Requires that you own the process or that you have GROUP
    privilege and that the process is in your group.

    Specifies the name of the process for which the characteristics
    are to be changed. Process names can be up to 23 alphanumeric
    characters long in the following format:

    [node-name::]process-name

    o  The node name can have as many as 6 alphanumeric characters.

    o  The colons (:)  count for 2 characters.

    o  The process name can have as many as 15 characters.

    A local process name can look like a remote process name;
    therefore, if you specify ATHENS::SMITH, the system checks for
    a process named ATHENS::SMITH on the local node before checking
    node ATHENS for a process named SMITH.

    The default process is the current process.

    Process names are unique only within a particular UIC group.
    You cannot specify the process name for a process outside of
    your group. To change the characteristics of a process outside
    of your group, you must use the qualifier /IDENTIFICATION=pid.
    The process name parameter is ignored. If you include neither
    the process name nor the /IDENTIFICATION qualifier, the current
    process is assumed.
