- Hi. I've used Windows MathCAD 3.0, and it has some nice features (like the
- Maple symbolic processor, Handbooks, the features left out of the crippled
- "Student" version for DOS, and the flexibility of choosing display and printer
- drivers, which applies to all Windows apps). However, I have a few gripes about
- MathCAD 3.0 (some or all of these may have been fixed in the newer version 3.1):
-
- 1. It is too bulky and slow (even for a Windows app running on an IBM PS/2
- model 70-386-25MHz) -- even when you're just typing stuff on the screen, it
- takes its own sweet time.
- 2. It isn't very keystroke compatible with the DOS versions -- since alt-keys
- (like alt-d) are reserved by Windows for invoking pull-down menus from the
- keyboard, I guess this is to be expected, but I haven't found any decent way to
- type in Greek letters -- What you have to do is pull up a dialog box or
- something and change the font for the current text region from Roman letters
- to Greek letters -- this means that you can't mix them (like for example,
- delta-x)! Maybe there is some way to do this, but I have not yet found it!
- 3. For operations such as cutting/pasting and dragging regions around the screen
- with a mouse, MathCAD insists on writing to two files to the directory specified
- by a certain environment variable (WMCADDIR). This is no problem for a single-
- user installation (i.e. when you dump it onto your own hard disk), but it makes
- it impossible to run MathCAD on a network or whatever in a write-protected
- drive! Even if the directory were writeable, you still couldn't have more than
- one user running MathCAD at a time, since one user's cuts or drags would
- overwrite another's! And if you change WMCADDIR to point to a writeable TEMP
- drive or to the currently-logged-in user's personal directory, then you can't
- use Maple or the Handbooks, because WMCADDIR also tells MathCAD where to find
- those files as well! Perhaps they have a network version which doesn't have
- these restrictions, but since we had enough copies for the number of machines
- that were running WMCAD, we (where I was before coming here to NC State)
- never looked into that. Instead, I wrote them a little assembly language TSR
- that made these files go to some other drive that was writeable, and this pretty
- much fixed our problems.
- 4. The documentation isn't very good -- it's more of a function reference, and
- it doesn't explain how to do basic things, like (2) and (3) above.
