/PRIORITY=n

    Requires ALTPRI (alter priority) privilege to set the priority
    higher than your current process.

    Specifies the base priority at which the created process
    executes.

    On Alpha, the value of parameter n is a decimal 0 to 63, where 63
    is the highest priority and zero is the lowest. Normal priorities
    range from 0 to 15; real-time priorities range from 16 to 63.

    The default priority is that of the current process.
