Syntax:

SELECT conditionalexpression

CASE test1

[statementblock]

[CASE test2

[statementblock]]...

[CASE ELSE

[statementblock]]

END SELECT

Parameter:

conditionalexpression, test1, and test2

A numeric or string expression.

Description:

This statement executes one of statementblocks depending upon the value of

conditionalexpression according to the steps below.

(1) SELECT evaluates conditionalexpression and compares it with

tests sequentially to look for a match.

(2) When a match is found, the associated

statementblock executes and

then control passes to the first statement following the END SELECT.

If no match is found, the

statementblock following the CASE ELSE exe-

cutes and then control passes to the first statement following the END SELECT.

If you include no CASE ELSE, control passes to the first statement following the

END SELECT.

• If the SELECT statement block includes more than one CASE statement contain-

ing the same value of

test, only the first CASE statement executes and then

control passes to the first statement following the END SELECT.

• If a

CASE followed by no executable statement is encountered, control passes to

the first statement following the END SELECT.

•

conditionalexpression (numeric or string) and tests must agree in

type.

Flow control statement

SELECT...CASE...END SELECT

Conditionally executes one of statement blocks depending upon the value of an expression.
