  The one-character special symbols used in the Mac version are mostly not 
available on the DOS window, and the ones that are have different ASCII codes
than in the Mac world.  So I got rid of most of them entirely in the X86
version, and replaced them with words.  In many cases, the function had
both a symbol to invoke it and a word, such as "degree", which had the
partial derivative symbol and the word Deg.  In those cases I simply use
the word.

  Here are the conversions from the Mac to the Windows version (revised 
October 20, 2004):

These connectives have a single symbol for the Mac, here they have
two (as in standard programming languages):

less than or equal       <=
greater than or equal    >=
not equal                <>

The boolean connectives are simple.  You don't need { } or anything else; just write 
complex conditions like:  if x = 3 + y and 4 = y - z then ....

Command-interrupt:  On the Mac, one can set a flag with the command
&(m=1) to allow user interrupt (and later resumption) of a long computation: 
to interrupt Fermat, you press the command key.  On Windows/X86 the same end is
accomplished not by pressing a key, but by moving the cursor (with the mouse) to
the left edge of the screen.  (Within 3 pixels of the left edge is good enough.)
To resume, MOVE THE CURSOR AWAY and then enter &_p.
