this is a stupid newbie question. working on my first app. never had to look at the clear, release, etc statements before. now i added some code, and when i try to exit my app there are all sorts of unknown references. what is the normal way to close an app? i do not even know what actually happens (which events are triggered) on a RELEASE.

in my case i have a toplevelform (osdi), with a pageframe. each page contains many containers and grids. these containers and grid use many of the variables and methods in a container that holds public methods and variables (oapp, below).

when i release osdi, should its pageframe, and all its containers and grids be destroyed? seems i end up in the debugger on osdi.page2.grid.valid during the clear all.

CLOSE ALL
RELEASE oSDI && toplevelform
RELEASE oApp && container, pulblic methods and variables
CLEAR ALL
RELEASE ALL

any info is appreciated.
