A function that gives a directory of 41CL ram pages that have data stored on them. After a while, someone might forget if they have copied something to 806,809, etc. What ram pages have been used so unused pages can be found?

:-)

The only way that I can think of to do something like this would be to reserve a RAM page to hold some kind of "valid" bit corresponding to each RAM page. You would need to manually set/clear the bits as you used pages though. Conceptually it's not much different from what I do in the Image Database and the Flash Database.
