I believe that the maximum size of the datalog is 2033 entries, minus
whatever you need for program data.
If you want to figure this out dynamically from the PC, get the memory map
after downloading all programs to the RCX. The maximum datalog size is
then (map[93] - map[90] - 2) / 3.
If SetDatalog fails to allocate space, I believe the previous datalog is left
intact. But I could be wrong about that.
