Portal or Related Record Detection

Hi

Somewhile back I was working on a generic script to strip formatting from fields and wanted to be able to deploy it in any db on any layout without making any changes to the routine. I got it to the point where it would work for any layout, with any number of fields, even repeating fields. But I never cracked the logic that would detect portals and allow me to loop through fields in portals to "TextFormatRemove" on all of them. Is there some function I have missed? or some logic?

I guess what I am wanting to ask, indirectly, is are there any fields from related records on this layout and, if so, what portalrow# are you (if any).

Clearly the problem is solvable with a full tab order including all fields, but not every layout will have every field in the tab order. The goal was a universal, context-independent de-formatter. I can't stop thinking that it is possible.

A sample file is attached.
