ELSE IF

Purpose

The ELSE IF statement is the first statement of an optional ELSE IF block within an IF construct.

Syntax


>>-ELSE IF--(--scalar_logical_expr--)--THEN--+-------------------+-><
                                             '-IF_construct_name-'

IF_construct_name: is a name that identifies the IF construct

Rules

scalar_logical_expr is evaluated if no previous logical expressions in the IF construct are evaluated as true. If scalar_logical_expr is true, the statement block that follows is executed and the IF construct is complete.

If you specify an IF_construct_name, it must be the same name that you specified in the block IF statement.

Examples

IF (I.EQ.1) THEN
    J=J-1
ELSE IF (I.EQ.2) THEN
    J=J-2
ELSE IF (I.EQ.3) THEN
    J=J-3
ELSE
    J=J-4
END IF
