  What is the difference between scan and \?

  show USTour:([]StartCity:`Boston`NewYork`Washington`Miami`Austin`Chicago;EndCity:`NewYork`Washington`Miami`Austin`Chicago`Boston;wp:0 1 1 1 1 0)
  show route:USTour[`StartCity]!USTour[`EndCity]
  route scan `NewYork //returns `NewYork`Washington`Miami`Austin`Chicago`Boston</pre><p>In this situation, I can't seem to use the backslash (I get an error). However, if I want a termination condition (a while loop!) then I need to use the backslash:</p><pre>(`Austin <>)route\ `NewYork //returns `NewYork`Washington`Miami`Austin

  How can I know which one to use? When is the backslash interchangeable with scan?
