The most important thing to remember about the scanner is that 

nothing happens

unless the special character is seen.

  There are no funny sequences that will

cause strange things to happen. The best way to view a FunnelWeb document at

the scanner level is as a body of text punctuated by special sequences that serve

to structure the text at a higher level.

The remaining description of the scanner consists of a detailed description of the

effect of each complex special sequence.
