This package includes:
------------------------
MG.001 File used by MASTER-GRAPH (tm).
MG.002 File used by MASTER-GRAPH (tm).
MG.003 File used by MASTER-GRAPH (tm).
MG.DOC This file you are now reading.
MG.EXE NON CO-PROCESSOR (80287/387/486) version of MASTER-GRAPH (tm).
MG.NFO Tiny information file.
MG87.EXE Numeric CO-PROCESSOR (80287/387/486) version of MASTER-GRAPH (tm).
General information
---------------------
1. If you run MASTER-GRAPH (tm) not from your current directory,
be sure to set the MGDIR parameter in the environment set.
For example: SET MGDIR=C:\MG\
2. MASTER-GRAPH (tm) requires an IBM AT, PS2, 386, 486 or a 100% compatible.
Starting from version 4.10 old XT machines, based on the 8088/8086 chips,
are NO longer supported.
3. MASTER-GRAPH (tm) requires MS-DOS version 3.30 or later (MS-DOS 5.00 was
also tested successfully) or OS/2 2.0 GA release.
Testings approved that MASTER-GRAPH (tm) may also be executed under
DESQview and WINDOWS 3.xx provided there's enough memory.
MASTER-GRAPH (tm) was also well adjusted to running in the DOS session
under IBM's OS/2 2.0 GA (both in a window and on a full screen).
4. At least 256Kb free ram memory is required to run MASTER-GRAPH (tm).
-------------------------------------------------------------------------------
Additions in version 4.10 over version 4.02:
============================================
1. Code now uses 80286 instructions to provide faster performance and smaller
code size. 8088/8086 computers will not be able to execute this version.
2. Enhancements and speed improvements in the graph analysis operation.
Also now a limitted analysis can be done with more than one graph on the
screen, and with X= expressions.
3. Color support for the initial screen.
Additions in version 4.02 over version 4.01:
============================================
1. When analysing a plotted graph (pressing F3), now you can press ALT+S
to swap the location of the analysis window from the bottom of the screen
to the top of the screen and vice versa.
2. A new built-in function: COTH(x) = Hyperbolic Cotangent.
3. A new built-in function: CUBE(x) = x^3.
4. Fixed some overflow problems and run time errors.
5. Improved handling the MGDIR parameter in the environment set.
6. Little changes in the help text.
Additions in version 4.01 over version 4.00:
============================================
1. Tiny bug fixes and help text changes.
2. A special functions stack saves the last 10 plotted functions.
You may move inside this stack with the UP and DOWN arrow keys.
3. MASTER-GRAPH (tm) no longer sets and resets the NumLock key's status.
This operation was done before to assist users with old 80-keys keyboards,
but since all standard keyboards nowadays are enhanced, there is no need
for this operation any more.
4. Help text is now referred in a more efficient way.
Additions in version 4.00 over version 3.30:
============================================
1. A Microsoft/Logitech mouse is now fully supported.
If you have a three button mouse, your middle button can be used to
invoke the on-line help screens.
When a Y/N question is given, the RIGHT button performs as NO and the
LEFT button performs as YES.
2. Added ALT+M to invoke a menu (can be accessed also by clicking the left
mouse button at the upper left corner of the screen).
Menu items can be selected by either pressing the corresponding hot key,
pressing the first letter or clicking the left mouse button.
3. Fixed a bug in auto-scaling that would lock the computer.
Fixed a bug in the PERFECT accuracy warning.
Fixed a bug in loading help if the current directory changes.
4. Added X and Y labels to the axes (when axes are displayed).
5. A new built-in function: INV(x) = 1/x
6. A new built-in function: SINC(x) = SIN(x)/x
Note: This function is defined as 1 when x=0
7. On-line help was re-arranged and enhanced to support the new changes
with the mouse, and the new options.
8. Code is now compressed so that minimal disk space is required.
Additions in version 3.30 over version 3.20:
============================================
1. Higher performance & smaller code using Turbo Pascal 6.01
2. The VGA/EGA version now works on every VGA/EGA.
3. Minor changes in the help screen of the VGA version.
4. Bug fixed in handling negative power calculations.
5. A new built in function: CURT(x) = Cube root of x.
Mathematical meaning: CURT(x) = x^(1/3)
6. A new built in function: STEP(x) = Unit step.
┌ 1 if x>=0
Mathematical meaning: STEP(x) = │
└ 0 if x<0
This function will allow you to define functions in a specific domain.
Example 1: ┌ SIN(X+π/3) if X>=3
The function: │
└ 0 otherwise
can be defined in MASTER-GRAPH (tm) 3.30 by:
Y=SIN(X+π/3)*STEP(X-3)
Example 2: ┌ 3*X^2 if -5<=X<6
The function: │
└ 0 otherwise
can be defined in MASTER-GRAPH (tm) 3.30 by:
Y=3*SQR(X)*[STEP(X+5)-STEP(X-6)]
Example 3: ┌ 3*X if -2<=X<2
The function: │
└ 5 otherwise
can be defined in MASTER-GRAPH (tm) 3.30 by:
Y=5+[STEP(X+2)-STEP(X-2)]*(3*X-5)
