            srv_use_stored_prim. The variable stored_prim_write indicates
            the number of stored primitives, which are not indicated as
            to be read again (by function srv_use_stored_prim).

+--------------------------------------------------------------------+

  PURPOSE : create a frequency hopping list from channel list and
            mobile allocation. The mobile allocation is a bitmap.
            if the n-th bit of the mobile allocation is set to zero,
            the n-th channel in the channel list is not member of the
            frequency hopping list. If the n-th bit of the mobile
            allocation is set to one, the n-th channel in the channel list
            is member of the frequency hopping list.

            e.g:    channel list has the members 10,20,30,40,50,60,70 and
                    in the mobile allocation the bits 1,3 and 4 are set           :

            channel list:        10  20  30  40  50  60  70
            mobile allocation:    0   1   0   1   1   0   0

            that means the hopping list is 20, 40, 50.

            The format of the mobile allocation is an UBYTE array with the
            end identifier NOT_PRESENT_8BIT (0xFF).

            The function returns TRUE if the Mobile Allocation is in one
            frequency band. If the Mobile Allocation is spread over multiple
            frequency bands FALSE is returned and the values returned are
            invalid.
