Interesting idea. I'm reading several small (200 lines or so) text
files into the stem variables and then looping through them repeatedly.
Some of the text files are "master" HTML files which contain tags where
I insert links into a database (I generate one HTML page for every item
in the database). One of the files is a "parameter" file that specifies
things like fonts to be used in the HTML (there's a default section plus
individual sections for every item category in the database). I don't
need random access; I only have to read the files sequentially, albeit
repeatedly.

Where do you get these ideas? What was in that muffin?

I haven't used REXX queues; guess I'll have to take a look at them. The
Warp 4 online help for REXX covers QUEUE, QUEUED and RXQUEUE, and from
those three pages I deduce that I'd have to PUSH a line back into the
queue every time I PULLed it out, and use some kind of a marker to
indicate when I was at the start/end of my data (sort of a circular
buffer without random access or ability to start at the beginning).

Eat another muffin and figure out how I can do this. :)
