First, Have you upgraded Windows XP to Service Pack 2, by any chance?
I'm getting programs that won't run reliably, or at all since I
upgraded. See the note regarding SP2 on the AADE site for the Filter
program.

Second, A workable solution for running DOS programs under XP is
DOSBox, now at version 0.65. Wes, W7ZOI's programs, along with the
legacy DOS programs on the RF Cafe site will run under DOSBox. The
problem in those particular cases is that XP makes them run full
screen, and you can't get screen captures of the results. With
DOSBox, the programs run in a virtual DOS environment in a window, and
you can get screen captures (alt-printscreen, and open up MSPaint or
other graphics software and paste the clipboard into the new blank
drawing that appears. As a virtual DOS environment, DOSBox does have
"DOS" memory limits and speed issues. Reg's programs should run with
no problem in DOSBox. See Wes's website at
http://users.easystreet.com/w7zoi/ , and on the main page, scroll down
to "Some Technical Notes". The problem and solution are described in
detail there.

Hi All,
I have used Reg Edwards programs before with great success,
Now I get the following error message.

16 bit MS-DOS Subsystem

The system file is not suitable for
running MS-DOS and Microsoft Windows applications.

What's wrong?
Thanks, Mike
