Caution:  ''Nested switches do not work because of the way the CON compiler compiles them''. A workaround is to put the nested switch in a seperate state, and call that state from inside the first switch.
The '''case''' keyword works like an [[ifvare]] statement, and '''default''' operates on every possibility that is ''not'' specified by a case statement. Each case block must be terminated with a '''[[break]]''' statement.


Also, putting extra [[break]] statements inside a case argument will cause a lot of errors. Again, the workaround is to put the commands that need to be seperated in another state, along with the break.

The switch statement in CON is similar to that in C. 

 switch <gamevar>
   case <constant>
     <do something>
   break
   case <constant>
     <do something>
   break
   default
     <do something>
   break
 endswitch

The case keyword works like an ifvare statement, and default operates on every possibility that is not specified by a case statement. Each case block must be terminated with a break statement.
