I downloaded this windows based doom editor (rgdmed06.zip)from
ftp.uwp.edu and couldn't use it because I didn't have a library file
called CMDIALOG.VBX, so I emailed the author and he asked me to post
to this group that he would include the necessary library files
in his next release (rgdmed07.zip).
I have since found the file I needed and took a look at this
editor, it looks like a very nice windows based object, graphics,
and level editor. The shareware version appears to let you insert,
delete, and move objects as well as view object bitmaps from the WAD
file and also get high res printouts of the level maps.
The author's email address is pan...@utkvx.utk.edu if you have
any questions. His news site is unable to receive alt.games.doom.
