Way too easy. 

how do you declare a variable for storage in the context of the caller?
(using a function)...
???

The DebugPush & DebugPop routines I used needed to store
the current func's flags in it's context -- I found it very troublesome
inside a function, to store a value into a local variable in the caller.
