    ■ testexpression      Any numeric or string expression.
    ■ expressionlist1     One or more expressions to match testexpression.
      expressionlist2     The IS keyword must precede any relational operators

    ■ statementblock-1    One or more statements on one or more lines.
      statementblock-2
      statementblock-n
 
    ■ The expressionlist arguments can have any of these forms or a
      combination of them, separated by commas:
 
      expression[,expression]...
      expression TO expression
      IS relational-operator expression
 
          expression             Any numeric or string expression compatible
                                 with testexpression.

        CASE IS >= 5
            PRINT "Maximum risk and potential return."
            PRINT "Choose stock investment plan."
 
        CASE 2 TO 4
            PRINT "Moderate to high risk and potential return."
