All of these help screens are edited and expanded versions of 
DOS information HELPS.
They should be copied using the DOS COPY command into the help directory,
C:\helpdir\dos.cat, and the table of contents file, CATEGORY.TOC, is rebuilt
the first time new files appear in the above help directory.

Alternatively, a new sub-directory, e.g. c:\helpdir\updates.cat, could be
made and these files could then be copied into it.  This would protect the
original terse and incomplete HELPS that AT&T wrote.  However, this adds an
extra menu level to the help utility where one would first choose the
category.  Personally, I find extra layers of menus unproductive and
user-difficult; for this reason, I don't like Wordperfect and its TOO
many nestings of menus.
