Re: A XyWrite for Windows installer

[Edward Mendelson <em36@xxxxxxxxxxxx>]

Thank you, Dave. In fact my installer now sets up the PATH16 variable 
and adds the correct PATH line to C:\otvdm\C\autoexec.bat, so there's no 
need to change XWSTART.INT file in order to use the speller.
What I plan to do, if the installer finds an existing installation, is 
this: the installer will offer to create a folder named 
Backup-2020-01-21-16-05-23 (or whatever the current date and time is) 
and copy all those changeable files into it, and then, after finishing 
the reinstallation, it will offer either (1) to copy your old versions 
of those files from the Backup folder into the main directory again 
(after copying the default versions into a folder named DefaultFiles or 
something like that) or (2) to leave those files in the Backup folder 
for you to restore (if you want them) one-by-one or by comparison with 
the default versions.
