Ah. Now that makes sense. I need to know the line numbers because I'm using this information to build a report of what is wrong in the file. Will need to rethink this (yet again). I guess I'll start with trying to process using HTS file constructor and count newlines as I go.

You really should make HST keep track of what line it is on...because that's what I need!  ;)

Other suggestions on how to build this wheel would be more than welcome. Thanks Ovid.
