Transformational Intrinsic Function (Generic): Returns the number of images.
The result type is default integer. The result is the number of images.
You can specify a compiler option or environment variable to modify the number of images. If both are specified, the environment variable setting overrides the compiler option setting.
A compiler option must be specified to enable coarrays. If it is not specified and you use this intrinsic function, an error occurs.
