DOS5ED is a program designed solely to patch a copy of the MS DOS 5.0
editor allowing it to list *ALL* of the files in the current directory
instead of just files with the .TXT extender by default when you select
'Open' from the file menu. QBASIC.EXE serves as both a general purpose
text editor and a BASIC interpreter for DOS 5.0, and the modification is
performed on a copy of your original. DOS5ED must be executed in the
same directory that QBASIC.EXE resides in (usually C:\DOS). Here is
what happens when you execute DOS5ED.EXE:
1. Display a brief summary of DOS5ED's purpose.
2. Ask the user if she/he would like to continue or abort.
3. If the ENTER key is hit:
A. See if QBASIC.EXE exists in the current directory.
a. If QBASIC.EXE is not found, notify user & quit.
B. Rename QBASIC.EXE as QBASIC.BAK.
C. Copy QBASIC.BAK to QBASIC.EXE.
D. Search for "*.TXT" in the new QBASIC.EXE
a. If its not found notify the user,
delete the copy of QBASIC.EXE &
restore the original.
E. If found replace "*.TXT" with "*.*" (wildcards)
& notify user of success.
4. If any other key is hit, abort.
To test it, simply type 'EDIT' at the DOS prompt, (or choose edit from
the shell) and select "Open" from the file menu. You should now be able to
see all of the files in the current directory within the file selector box.
The BASIC interpreter function of the editor is unaffected by the patch.
DOS5ED was written in MS QuickBasic 4.5 using routines from Crescent
Software's Quickpak Professional Library.
