Objects private to a program

Program objects such as global variables, module variables as well as resources used by the user interface and SQL connections and cursors, are private to a program.

This implies that each of these objects requires private memory to be allocated. If memory is an issue, do not allocate unnecessary resources. For example, don't create windows / load forms or declare / prepare cursors until these are really needed by the program. When the resource is not longer needed, consider freeing them (CLOSE WINDOW, FREE cursor).
