 > How do you search for/replace the end of line

To search for end-of-line, use the built-in SEARCH.  For example,
	<DO>TPU POSITION(SEARCH(LINE_END,FORWARD));
For a replace, you'd need something like:
	<DO>TPU POSITION(SEARCH(LINE_END,FORWARD));COPY_TEXT("new text");
		MOVE_HORIZONTAL(1);APPEND_LINE;

TPU reads the whole file into virtual memory as part of READ_FILE.  You
can't get there from here.  It could be worse: on some UNIX systems, ed
wants to read the whole file into PHYSICAL memory.
