MDEP is freeware. You may give copies of the program and documentation to your 
colleagues and students. 

Files on the MDEP distribution disk:

MDEP862.EXE: Main program.

MDEP862.OVR: Overlay file for the main program. Must be in the same directory 
as MDEP862.EXE.

and/or 

MDEP872.EXE and MDEP872.OVR (version of the program that requires numeric co-
processor. 

MDEPHELP.2: Help file for main program. Will be read only if in the same 
directory as MDEP862.EXE. 

INITPS.DEP: PostScript initialization file. Must be in the same directory as 
MDEP862.EXE. 

COPYMDEP.BAT: Makes a working copy of MDEP on another drive. See note below. 

USPOP.DAT: Sample data file.
HYPPAR.DAT: Sample contour data file.

GN.MDP: Sample CONFIG.MDP file. See documentation.

\BGI\*.BGI and \BGI\*.CHR: These graphics file are proprietary to Borland 
International and distributed only for use with MDEP in accordance with the 
Borland License agreement. For the main program to find them they must be 
either in the same directory as MDEP862.EXE or in a subdirectory directly off 
the main program's directory.

Notes:

1) COPYMDEP.BAT. This batch file takes one argument, the drive to which you 
wish MDEP to be copied. This batch file will copy MDEP862 and auxiliary files 
to the current directory on the drive you specify and create a subdirectory 
named BGI and copy the requisite graphics files to it. For example typing 

  COPYMDEP C:

at the DOS prompt will copy MDEP to the current directory of the C drive.

2) MDEP uses Turbo Pascal's system for detecting what graphics adapter is 
present in a computer. It usually works well but certain brands of VGA boards 
seem to fool it. If you have a VGA board and MDEP graphics come up in EGA, or 
worse, then use the Ctrl-A command (see documentation Part 8) to change to 
VGA. This has thus far always succeeded in putting the program in VGA. 

Addendum to the documentation

The trajectory (J) command that plots solutions through a lattice of points 
has been enhanced so that the user can specify the number of points used in 
the lattice. Entering an integer value n in the Other Parameters (R) menu on 
the graphics screen or the Graph-Settings-Coord/Ticks/Other menu on the 
function screen results in an n by n lattice being used. The graphics screen R 
menu is new and not yet documented. It also contains the graphics TOL 
parameter that was formerly on the Window menu (W) and the Contour Resolution 
parameter which was not previously available on the graphics screen.
