I have decided to add things to the standard DOS 6.22 Help file (HELP.HLP).
Most of this comes from these sources
1. commands.txt (in the MSDOS supplement package)
2. assorted Win9x readme files
3. MGDX's page on msdos.sys
The idea is, that if you install the qbasic.hlp system, you would have relevant information for the more recent Windows. Since the 'edlin' command from WinNT is not only DOS compat, but runs under MS-DOS 5 and above, and PCDOS 5,0, i have included these docos as well.
It also has the feature of being quite usable as an EDIT.HLP as well. This means that if you patch the clear string EDIT.HLP to HELP.HLP in QBASIC.EXE, and use my form of the help file, the qbasic editor will allow you to have the help page open when you edit files.
It has all of the error messages in the correct place, for the QBASIC, EDIT and HELP systems, also it has a much better documentation file for making these files.
