Anti-Distinctlyminty

Soooo, I'm not entirely clear on the workflow here…(I appreciate that I may be jumping in the at the deep end here)
In the supplied TOPs_GeoImport_Fixed.hip is it essential to write the geo to disk? I know that memory shouldn't really be an issue, so I am just using a File Pattern TOP and Geometry Import TOP, and in /obj/geo1/Initalize the file path is set to
`pdginput(@index, "", 1)`.
So, my main questions are…

1. Does this setup doing anything dangerously stupid?
   
2. Is pdginputa function that somehow knows what files a particular TOP node has input/output depending on when the expression is called in the evaluation chain?
   

Just coming back to this and trying to wrap my head around things and I noticed that the documentation is a little wonky. Current version of the docs for pdginput [www.sidefx.com] state that we have three arguments; index, tagand localize. But in the detailed explanation of those arguments it lists; name, indexand localize

I spoke too soon. It hung again…I will try to reproduce.
