ELSEWHERE

Statement: Marks the beginning of an ELSEWHERE block within a WHERE construct.

Syntax

[name:] WHERE (mask-expr1)
     [where-body-stmt] ...
[ELSEWHERE (mask-expr2) [name]
     [where-body-stmt] ...]
[ELSEWHERE [name]
     [where-body-stmt] ...]
END WHERE [name]

name
Is the name of the WHERE construct.

mask-expr1, mask-expr2
Are logical array expressions (called mask expressions).

where-body-stmt
Is one of the following:

• An assignment statement of the form: array variable = array expression.

  The assignment can be a defined assignment only if the routine implementing the defined assignment is elemental.

• A WHERE statement or construct

Rules and Behavior

Every assignment statement following the ELSEWHERE is executed as if it were a WHERE statement with ".NOT. mask-expr1". If ELSEWHERE specifies "mask-expr2", it is executed as "(.NOT. mask-expr1) .AND. mask-expr2" during the processing of the ELSEWHERE statement.
