  Opihi shell variables (scalars):

  The Opihi shell can have variables which are designated by a word
following a dollar sign: $foo.  Certain Mana function create and set
variables (ie, stats, cursor).  You can also set a variable to the
result of an arithmetic expression or just a number like this:

  $foo = 10.0
  $bar = 5*$foo + 0.6

Mana will replace the variables on a line before executing a command.
