MPP and MPP3D are computer graphics programs installed on the IBM computers in the Bell Hall Technology Center (in the annex to Bell Hall). There are three main applications: vector fields, contour diagrams, and 3-dimensional surfaces. The vector fields will probably be the most useful.

General directions

On an IBM-compatible in BHTC, click on an icon for the C: drive (it might be called something like (bhtc)C:). Then click on the directory named "mpp". In that directory click on mpp.exe (for contours or vector fields) or mpp3d.exe (for 3-dimensional surfaces).

There is also a documentation file called mpp.doc, though it may not be necessary. If you do want to read mpp.doc on the BHTC computers, click on its icon, which will put you in a word-processing program that cannot read it--DON'T PANIC--after clicking "ok" a bunch of times, you will be asked what format this file is in--click on the top choice "Plain Text" (note that if you copy this and bring it to a non-windows computer, you can just type out mpp.doc and read it the old-fashioned way), and away you go.

You may copy mpp to take to your home computer. Copy everything in the mpp directory. There are some warnings in various documentation files telling you what capabilities your computer needs. As best as I can tell, your computer is probably up to the job.

Specific features

Vector fields (as in Chs. 17, 18):
This can be found in the MPP program, and is pretty self-explanatory; probably the fastest way to learn is to play around. Two commands that you might not figure out right away: "H" for help (brings up a menu reminding you of other commands) and "I" for input (meaning you get to input the window size and functions, etc. again). You may have to hit the space bar (or some other neutral button) to wake it up first. The "ESC" button may exit some features that seem to have no exit.
Contour diagrams:
This is also in the MPP program, and, in theory, should be just as easy and self-explanatory as vector fields, but in practice, I found many bugs and flaws. Don't say you weren't warned. I will be looking into what's going on.
3-dimensional surfaces:
This can be found in the MPP3D program, and seems to be about as easy to work as the vector fields, and also seems to always work. It does everything the BHTC Macs 3-d graphing calculator can do, but more slowly. So I'll continue to recommend the Macs graphing calculator
