When trying to read in a file with the Arg Setfile function, an
improper filename returns an operating system error. If the Microsoft
editor (M) is in split-screen mode, any horizontal divider bars are
lost in MEP. The error contains the two following lines, which cause
the screen to scroll one position erroneously:

   Next filSYS1041: The name specified is not recognized as an
   internal or external command, operable program, or batch file.

In M, screen integrity is preserved, but the following error is
returned:

   Bad command or filename.

For example, invoke arg (ALT+A) to start an argument and enter about
20 or so shifted numbers (e.g. ^&%$&^%$^%$#^%$#^%$@%(^&*(*^&&*), and
then invoke Setfile (F2).

The screen becomes corrupted and the next keystroke may crash the
editor with an integer divide by 0 (zero).

Microsoft has confirmed this to be a problem with the Microsoft Editor
Version 1.00. We are researching this problem and will post new
information as it becomes available.
