Help using Ranges

[Zachary Kurmas]

Can someone point me to a more complete example of how to use ranges?  When I try to run the example from the documentation


#|kawa:1|# ("ABCDEFG" [1 by: 2 <: 7])

I get the error shown below.  Am I missing an include or something?


/dev/stdin:1:22: warning - no declaration seen for :
/dev/stdin:1:22: unbound location: :
        at gnu.mapping.SharedLocation.get(SharedLocation.java:22)
        at gnu.mapping.DynamicLocation.get(DynamicLocation.java:28)

#|kawa:2|#

Thanks,

Zack
