-1

Category

Language element control

Purpose

Executes each DO loop in the compiled program at least once if its DO statement is executed, even if the iteration count is 0. This option provides compatibility with FORTRAN 66.

-qonetrip is the long form of -1.

Defaults

The default is to follow the behavior of later Fortran standards, where DO loops are not performed if the iteration count is 0.

Restrictions

It has no effect on FORALL statements, FORALL constructs, or array constructor implied-DO loops.
