Dave,

Program(-1) (or negative anything for that matter) all seem to return the same as program(0) - the top level program. Did I misunderstand something?

>>thanks - that works ... but ... is ther any way to tell what nesting level my program is at? If not, with it working the way you've outlined, how to I move "up" a specific number of steps up the call stack? In other words, how can I return to the program "that is 4 level above me" for instance?
