SPACE range

    Deposits a value for a specified range of SPAM entries; it is
    valid only if the current page is a SPAM page. (The SPACE and
    DATA parameters are the only ones that you can use in DISPLAY
    and DEPOSIT commands that access a SPAM page.) The range value
    can be an asterisk (*),  referring to all entries, or a set of
    consecutive entries, which you describe as follows:

    lower-data-page-number[:higher-data-page-number]

    Each entry on a SPAM page consists of 2 bits, containing a value
    0 through 3 that represents a fullness threshold. For example, if
    the nth SPAM entry contains a 2, it means that the nth data page
    in the interval has reached a percentage of fullness greater than
    the second threshold for the area, but less than or equal to the
    third threshold.
