Case

The case statement is used to specify an action to take when the value examined by the select statement matches the particular case value. The following example from the book shows this:

select hour
   case 1: print "one";
   case 2: print "two";
   case 3: print "three";
.
.
.
   case 12: print "twelve";
print " o'clock."

Each case statement permits one statement. If more statements are required for any case label, the block should be encapsulated by { before the start of code for the particular case value and } at the end of the code for that case value.

Unlike the C programming language, the match of a case value executes only the code for that value in that select statement; other cases are not executed; execution continues with the next statement after the select statement.
