DOCASE, CASE, BREAK, ENDCASE
 ================================================================
 This command structure is like a multiple IF. It lets you choose 
 easily between more than 1 choices. The format is as follows:

   DOCASE   Argument
     CASE   Operator Argument
            (commands....)
            BREAK
     CASE   Operator Argument     <- you may have many case statements
     CASE   Operator Argument
            (commands....)
            BREAK
   ENDCASE

 Example :

   TestVar = "TEST"

   DoCase $TestVar
     Case = "Wrong choice"
     Case = "Another wrong choice"
        Say "This is never happenn"
        BREAK
     Case = "TEST"
        Say "Yes, this is the one!n"
        BREAK
   EndCase

 The above should print the word "Yes, this is the one!"

 You can have as many case statements as you want.
 These are  OPERATOR  you can use (same as IF and WHILE).

 You can have DoCase within DoCase etc...

 When docase finds a case which is true, it will start executing 
 until it encounters an ENDCASE or a BREAK. - like in a C program

 This means that you can have multiple case arguments in a row (as
 is done above in the first 2 cases), and the code following will be
 executed if any one of them is true.
