1.1       root        1: #print
                      2: You may have noticed that neqn threw away the spaces
                      3: in several of the examples we did.  For example, in
                      4: .EQ
                      5: a = b + c - d
                      6: .EN
                      7: the output equation looks like
                      8: a=b+c-d
                      9: regardless of spaces in the input.
                     10: 
                     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
                     16: one.
