Description

Branching to each statement is done in accordance with the result of the <Expression>.

An integer value or a formula can be specified in the <Expression>.Processing will branch to the <Value> of Case that matches the result.

When no formula matches, processing branches to that defined by Case Else.

Multiple Case statements can be used.

The Case statement and Case Else statement can be omitted.

The End Select statement can be omitted.

When multiple expression results exist that match the Case statement <Value>, only the first Case statement from among them is executed.

Moving control from outside the Select block to the inside or moving control from inside it to the outside using statements such as the goto statement is not possible.
