(5) CASE conditional syntax
(a) Format
CASE <Integer expression> OF
<Integer selection 1> : <Syntax 1 ...>;
<Integer selection 2> : <Syntax 2 ...>;
·
·
·
<Integer selection n> : <Syntax n ...>;
ELSE
<Syntax n+1 ...>;
END_CASE;
(b) Description
The result of the CASE conditional expression is returned as an integer value. The
CASE conditional syntax is used to execute a selection syntax by a single integer value
or an integer value as the result of a complicated expression.
When the syntax that has the integer selection value that matches with the value of
integer expression is executed, and if no integer selection value is matched with the
expression value, the syntax that follows the ELSE syntax is executed.
(c) Example
(6) FOR...DO syntax

of a repeat variable.
