-
- Please let Mathematica allocate as much memory as possible.
- Conventional wisdom says 8Mb is adequate. You can check the value
- by clicking once on the Mathematica icon and select the Get Info
- option from the Finder's File menu. It is the number that appears
- in the lower left-hand corner of the info window.

- --> Warning
-
- A warning about opening some Notebooks under Mathematica 2.0.
- The new version of Mathematica changes the storage of PostScript
- graphics. PostScript graphics are now stored WITH the 20 kb header that
- was "assumed" to be there under Mathematica 1.2. When you open a 1.2
- Notebook under 2.0, Mathematica will prepend this 20 kb to each
- PostScript graphic and render the graphic. Therefore, those
- Notebooks containing many graphics cells will take a long time to
- open under Mathematica 2.0. It also means that Notebooks will grow in
- size. Some of the signal processing Notebooks will quadruple in size,
- thus overwhelming the machine.

-
- --> Suggestion
-
- Please, please, use lower case one-letter symbols as
- variables and do not assign values to them. This includes variables
- like n, t, x, and y, as well as t1, t2, etc. Use one-letter upper
- case variables to represent constants (A, G,...), although Mathematica
- reserves I and N and we reserve L and Z.
