reading parts of a large data file

@Gordon,

does

but it also means that any ... stored in and executed from external flash

mean that it is an either-or ?

Since this creates dependencies between various things and mostly between the way code is done and built static and uploaded or dynamic at runtime, it is important have the setups and coding documented to not create confusion.

I hope my paranoia of experiencing unpredictable / unexplainable effects as a plain js user will evaporate like fog in the sun the moment I understand better that constraint.
