Users of MYDOS who have been having problems with funny characters appearing
in their text may find the solution to their problems in the following:

I had been getting occasional extraneous characters on my printer when copying
a file to the printer.  Under some conditions, these characters also appeared
in disk files and could be seen with an editor.  Typically it would be a
single character like R or 1, repeated periodically throughout a file or
printed document.  Needless to say it was both mysterious and annoying.

Yesterday I received a tip from Paul Swanson, a local hardware/software guru
(who is also an Atari dealer, by the way).  The culprit seems to have been
a bug in MYDOS which causes it to work incorrectly when the data flow is
through the 850 interface.  I rebuilt my word processor disk, which I had set
up with MYDOS, to use vanilla Atari DOS 2.0S, and the problem seems to have
cleared up.  I believe the problem also occurs on a terminal emulator disk
which is also built with MYDOS.  I have not had a chance to see if the fix
works there also.
