 dit(code(arithmetic_basicspace) and code(arithmetic_multiplier))
 The space taken by a note is determined by the formula 
-verb(arithmetic_multiplier * ( c + time ))
-where code(time) is the amount of time a note occupies.  The value of
-code(c) is affected by code(arithmetic_basicspace).  Increasing
-code(arithmetic_basicspace) will increase code(c).
