In order to force the compiler to interpret our example the other way around, we
have to write it explicitly:
have to write it explicitly:

SELECT CASE STATEMENT
Use the
select case
statement to pass control to a specific program branch, based
on a certain condition. The
select case
statement consists of selector expression
(condition) and list of possible values. The syntax of the
select case
statement is:
select case selector
case value_1
statements_1
...
case value_n
case value_n
statements_n
[
case else
default_statements]
end select
selector
is an expression which should evaluate as integral value.
values
can be
literals, constants or expressions and
statements
can be any statements. The
case
else
clause is optional.
First, the
selector
expression (condition) is evaluated. The
select case
statement
then compares it against all available
values
. If the match is found, the
statements
following the match evaluate, and the
select case
statement terminates. In case
there are multiple matches, the first matching statement will be executed. If none of
the
the
values
matches the selector, then
default_statements
in the
case else
clause (if there is one) are executed.
Here is a simple example of the select case statement:
select case operator
case "*"
res = n1 * n2
case "/"
res = n1 / n2
case "+"
res = n1 + n2
case "-"
res = n1 - n2
case else
res = 0
cnt = cnt + 1
cnt = cnt + 1
end select
