Frill Processing

Question

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 text here(is set more than once on current page), In Frills processing . Right now the is outputting the same text on all instances where the text is getting captured.

Luke,

Frills processing is indeed an exciting world.
And did anybody tell you that this is best done using xyPerl?

And now for your question:
There is only 1 text register from which you can read the content line by line and that is text register 0.
So in the main text you would have several instances of <px;;0>text here<pa>.
And when doing your frills processing loop going over all of the main stream lines, you can call back the 'current' content of text register 0 using <tr;0;f>.

If your needs exceed the use of a single text register, you can think of several xyPerl constructions that might do the trick, which then might break if you compose things out of order.

Anyhow the XPP macro language only gives you this 1 'special' text register (the documentation refers to this use as valid for using margin notes)
