I'm using (Zenith's release of) MSDOS v3.1, with (Zenith's version of) a CGA
card.  I do just this in my AUTOEXEC.BAT file; the very first line is "echo
off" and a subsequent line defines a fairly long and involved prompt (33 char's
that set up four different colors...).  It works fine for me.  The differences
that I can see between my .BAT file and the example are that my "prompt..."
command is on a line by itself rather than being the end of an "if" statement,
and I have some other "echo..." commands between the initial "echo off" and
the "prompt..." (intermediate colors, etc.).

Which sort of brings me to my question/request.  A while ago there was much
posting about patches to make "echo off" the default.  I saw patches specifying
at least two different locations.  Unfortunately, _my_ MSDOS didn't have the
indicated original value in *either* location, so I haven't made the patch.
So, does anyone have an "echo off" patch that will work with Zenith's MSDOS
v3.1?  Even more important (to me), can anyone supply some context for this
patch?  That is, what are the preceding and following byte values?  Is the
value-to-be-changed in code, or a data table, or what?
