Stack space is memory that is used to pass function arguments, return
results, and temporarily store local variables. Since a very limited
amount of memory is allocated to the stack for programs on Palm OS
devices, and because it is often difficult to determine how many times
a recursive function will be called, recursive functions can be very
dangerous. I would avoid using a recursive function if that is at all
possible.

In C, there is very little difference between a pointer and an array.
So, you could use pointers. (For example, a linked list of "array"
elements.) However, see below...

Stringer's suggestion is a good one. Data stored by the database
manager is still RAM, so it is basically as fast as data stored by the
memory manager, *except* that the memory that the database manager
handles is protected and so there is a small amount of overhead to lock
and unlock the protected memory.
