        !             2: You may have noticed that neqn threw away the spaces
        !             3: in several of the examples we did.  For example, in

        !             7: the output equation looks like
        !             8: a=b+c-d
        !             9: regardless of spaces in the input.

        !            11: Spaces are always thrown away, and so are new lines - you
        !            12: can type an equation on as many lines as you like.
        !            13: This latitude is permitted mainly to make it easy to type equations -
        !            14: longer equations are easier to edit when they are typed
        !            15: as a series of short input lines instead of one giant
