Each answer raises another question...
In my case, it's only a small amount of memory - 32 Booleans - and it would
be handy to have them set when the program starts, and survive during the
duration of the app running. So maybe a global array w/b appropriate. In
that case, I would guess that I should use a MemHandleNew for it, and lock
it only when I need to write to it (during AppStart, probably) or read from
it (just few places in the program), then MemHandleFree it when the app
terminates. Would you agree?
Thanks again - your quick and helpful replies are very much appreciated!
