I have the same problem for an FKEY and while I haven't tried it yet, I think
the answer is to create a resource for the System (or your own file) called
"mLng" or somesuch. If it exists, then use it as a scratch pad, if it doesn't
exist, then create it. Use ID 1000 or somesuch and you should be set... (I hope)
Let me know if this works or if someone else comes up with a better way, as
I need to use this too. (ever want an interactive profiler that can "zoom in"
on the most used memory locations and display a graph from a DA while your program
is running?).
