The demonstration uses a spreadsheet applet written by Sun Microsystems. We have interfaced MM to Lotus 1-2-3 97, but that can't be run over the Web in a portable way, whereas Sun's applet can.
If your browser can't run Java applets, you won't be able to run the demo. Also, if you are outside the UK, or have a slow link, you may find the applet takes a long time to load. In that case, you can view some screen shots of the applet, from an MM presentation.
I would be interested to have your criticisms on that and on the demo. I'd also like to have suggestions for joint research projects, if anyone experienced in spreadsheet modelling is interested in taking part in collaborative grants or software development.
The text editor will contain an MM program.
You can load the program into the spreadsheet by
selecting the Compile option on
the Compile menu.
MM will compile it, and then pop-up a window saying
Reloaded spreadsheet with
some more text saying which columns
the attributes have been allocated.
Click on the OK button, and
the spreadsheet will then run the new program. You can enter
new data directly into the spreadsheet, but only into the black (value)
cells, not the red (formula) ones. You will need to hit return
before the new data becomes visible and is acted upon. You may
find that the spreadsheet fields do not respond properly to
delete. This is not a problem with MM, but
with Sun's spreadsheet applet.
There are some other programs you can load. Do so by going to the
File menu, then Select file, then
compiling as before. Two of these were inspired by examples from
Richard
Knights' modelling examples at Devon
Curriculum Services.
