I believe I was unclear on both of my requests.  I meant I would like TPU
better if:

You could prevent TPU from reading in the entire document unless it becomes
necessary (EDT does this by default.  It only reads in the parts of a file
that it has to.  Once it has read it, it holds it i memory as does TPU,
but if I want to look at the first few pages of a huge listing with editor
functionality, I don't have to wait for EDT to read the entire listing before
I can look at the first page.  What I meant was that it ONLY reads in the
entire document if you do something like going to bottom of document forcing
the entire document to be accessed.

The second item was as follows:

In EDT, I can search for an end of line.  This means, I can replace double
empty lines with single empty lines.  I would simply replace "^M^M" with a
paste buffer containing a single empty line.  I can specify a high repeat
count and make this into a global search and replace.  Or I can globally
replace "^M^I" with a paste buffer containing an empty line, which removes
the first leading (or if I do it differently all leading) tabs from lines,
but leaves those internal to the line.

Or I can replace "^M" with a paste buffer containing a line "$EQU " to place
$EQU at the beginning of each line.  There are many more applications requiring
the ability to replace the end of line character.

The following quirks apply when replacing end of line in EDT:

If you are replacing a single "^M" with a large repeat count in order to
do a global replace, go to the end of document and do this in a reverse
direction, because there is always a single "^M" at the end of document,
and search and replace in forward direction on a "^M" by itself will cause
a limitless number of replacements to occur at end of document.  Also, you
do not type "^" and "M" in your replace strings.  You hit the return key
which echos as a "^M" or the tab key which echos as a "^I", etc.

If anyone knows how to do this in EVE or LSE (simply, without writing
TPU routines, I would greatly appreciate it.  I cannot use an editor which
cannot replace the end of line as an entity.

                                Thanks
