Technically, VOP is just a wrapper around VEX, so you could say that you're kinda using VEX... indirectly! :P
@Steven I actually didn't reply to your question at all. I don't know how I manage to misread emails that well but I'm pretty good at it! Anyways, the function `pcfind` returns point numbers, so then you can just loop over them and use the usual methods, such as for example `point <http://www.sidefx.com/docs/houdini/vex/functions/point>` to retrieve other attributes.
