Questions about using EIP mode

$

I was wondering if there is some sort of function or enviroment variable which tells my skill code that I am currently in EIP mode versus working currently in hierarchy level 0.

So far I was able to just check hiGetCurrentWindow()~>topcell==hiGetCurrentWindow()~>curCell .

Also , wondering , since I can't obviously use hiGetPoint()  when in EIP mode since that returns top level coordinates, I have to use (I think without looking) its hiGetEditToWindowPoint()

but I also noticed that hiGetWindowToEditPoint() does the reverse which (I think again without looking) you would pass to a child subcell coordinates from top level , but I cannot figure out

why someone would pass top level coordinates to a subcell.  What use would that be ??

Thanks for your consideration.
