 Limbo does not have a verbatim `switch` statement. Rather, it has a statement named `case` which is analogous, but not identical to C's switch-case construct. 
 
-Limbo case statements break by default and accept range matching operations involving the `or` and `to` keywords.
-
-Note: A break or continue followed by a label causes a break out of, or the next iteration of, the enclosing construct that is labeled with the same label.

 ### switch.b:16,31
 
+This segment exemplifies a few features of limbo's case statement. There is an iterative loop wrapped around a case statement which has a boolean `or`'d section and a default section, indicated by the wildcard `*` operator.

 ### switch.b:33,42
 
+This case statement demonstrates the use of the `to` range operator in a given section while providing a specific section to match the `C` character as well. 
 
-
 ### switch.b:44,51
 
+Limbo is able to switch on string values, this can include a `nil` check, demonstrated by the `""` section. Note that there is no default section provided. The default section is not mandatory.

 ### switch.b:53,60
 
+This case verifies whether a value is `0` or `1` to determine if a value is binary. 
 
-
 ### switch.b:62,69
 
+The valid types for case statements include: `int`, `string`, and `big`.
 
+Note that the `big` coercion statement is mandatory.

 ## Exercises
 
 - Try commenting out the `break` and/or `continue` keywords in the first switch, how does the behavior change?
+- Change the variable `c` to equal `'C'`, what's printed?
