1    /CUMULATIVE

       /CUMULATIVE[=n]
       /NOCUMULATIVE

    Tallies all stack PC values for each data point in the histogram.
    Thus, each bucket shows how much time or other resource is
    spent in the corresponding program unit and all program units
    it calls. The /CUMULATIVE qualifier has no effect if you are
    not plotting against the program address domain. To use the
    /CUMULATIVE qualifier, you must have collected stack PC values in
    the Collector. You may specify an integer to cuase only the first
    "n" routines down the stack to be used. If used with /STACK_
    DEPTH=m, the Analyzer will charge the data point to all calls (or
    "n" calls for /CUMULATIVE=n) below the specified depth.

    The /NOCUMULATIVE qualifier tallies only the original program
    counter value for each data point.

    Note that /NOCUMULATIVE, /NOMAIN_IMAGE and /NOSTACK_DEPTH are the
    default program address selection qualifiers.

2    /MAIN_IMAGE

       /MAIN_IMAGE[=n[:m]]
       /MAIN_IMAGE[=prog-unit]

    Specifies to use the first call stack PC value that falls in your
    program's main image, when tallying program addresses. You may
    specify the PC value to be n or the range n:m. If you specify a
    program unit or address range, it will select the first PC value
    in that address. The /NOMAIN_IMAGE qualifier specifies to use the
    original program counter value for each data point, to tally the
    data point.

    Note that /NOCUMULATIVE, /NOMAIN_IMAGE and /NOSTACK_DEPTH are the
    default program address selection qualifiers.

3    /STACK_DEPTH

       /STACK_DEPTH=n
       /NOSTACK_DEPTH

    Determines whether the Analyzer will climb the call stack to
    determine the PC values.

    Note that /NOCUMULATIVE, /NOMAIN_IMAGE and /NOSTACK_DEPTH are the
    default program address selection qualifiers.
