Known issues with Maple 5.4 Demo Version:

The following are some of the things that don't work:

  1. Cannot save files.
  2. Cannot export files.
  3. Digits (precision) <= 50
  4. animate() does not work. Note, however, that the following command does produce an animation: 
    for i from 1 to 10 do
  A[i] := plot(sin(x+i),x=-10..10)
od:
display({A[1],A[2],A[3],A[4],A[5],A[6],A[7],A[8],A[9],A[10]},
  insequence=true);
  5. limited support for packages (I have found support for finance, plots, linalg so far...)
  6. No terminal version
  7. Cannot print worksheets. Note, however, that you can still use the File -> Print Preview function you can then use a screen capture program, such as Screen Grab Pro to capture images of the workbook and post them in an html page...
  8. Cannot cut and paste examples from help
  9. No proc() function procedures.
What are the positives?
  1. It is totally free.
  2. The "help" section is very complete, even covers commands that the demo version does not support!
  3. You can create plots and copy them to the Windows Clipboard where they can be pasted into Wordpad. Make sure to select Options->Plot Display->Window first, then right-click the mouse to copy the plot.
  4. Supports a large set of Maple commands.
  5. Excellent for demonstration purposes
  6. Can be used for generating 2D and 3D plots (which can be "snagged").
  7. Can be used to create worksheets (but not to save them)
  8. Can read text files in .ms format.
  9. Can read in worksheets (downloaded from web) and execute them - as long as commands are supported. In fact, Maple5.4 demo can be configured as a "helper application" for the browser in Windows.
The biggest problem is to save your work between sessions. I have found one workaround: If you save a file, with the Maple ">" prompts, e.g. ex2.m, 
> plot(sin(x),x=-10..10);
> plot(cos(x),x=-10..10);
> plot({sin(x),cos(x)},x=-10..10);
in the directory MVR4DEMO (default installation directory) and then read in ex2.m as a "Maple Text" file, then the commands are read in in executable form.

It is not possible to cut and paste MapleVR4 text into or out of the demo application, but SnagIt has a "Text Capture" feature, which can be used to grab text in a user defined region. It then converts it to regular text on a clipboard, which can be pasted into a file and edited with notepade.exe or wordpad.exe...

If this does not work, you can always manually create the .ms maple file.
