The compiler treats the construction in this way:
if expression1 then
if expression2 then
statement1
else
statement2
end if
end if
In order to force the compiler to interpret our example the other way around, we have to write it explicitly:
if expression1 then
if expression2 then
statement1
end if
else
statement2
end if
Select Case Statement
Use the select case statement to pass control to a specic 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
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 rst matching statement will be executed. If none of
the values matches the selector, then default_statements in the case else clause (if there is one) are
executed.
