/EXTENT=quota

    Specifies the maximum size to which the image being executed in
    the process can increase its physical memory size.

    The default quota is that established at system generation time.
    The minimum value required for any process to execute is 10
    pages.

    Specify the value of n as a number of 512-byte pagelets on Alpha
    . Note that the operating system rounds up this value to the
    nearest CPU-specific page so that actual amount of physical
    memory allowed may be larger than the specified amount on Alpha.

    The extent quota is nondeductible.
