Frill Processing

I have entered the exciting world of frills processing.  I was wondering is it possible to output the value of a text register as it is set on the line that is being processed?  In main stream line <px;;80>text here<pa>(is set more than once on current page), In Frills processing <tr;80;p>.  Right now the <tr;80;p> is outputting the same text on all instances where the text is getting captured.
