Explanation These statements execute multiple command blocks in accordance with the
< expression > value. The setting method is as follows.
1. The < expression list > following CASE statement comprises multiple numerical
expressions and character expressions separated from each other by a comma ( , ).
2. If the < expression > value matches one of expressions contained in the
< expression list >, the specified command block is executed. After executing the
command block, the program jumps to the next command which follows the
END SELECT statement.
3. If the < expression > value does not match any of the expressions contained in the
< expression list >, the command block indicated after the CASE ELSE statement
is executed. After executing the command block, the program jumps to the next
command which follows the END SELECT statement.
4. If the < expression > value does not match any of the expressions contained in
< expression list > and no CASE ELSE statement exists, the program jumps to the
next command following the END SELECT statement.
