语法

pointer_bounds_form = NoPointerBounds | PointerBoundsSpec | PointerBoundsRemapping

Values

Value	Meaning
NoPointerBounds	the target is the pointer itself, p => a, or not a pointer.
PointerBoundsSpec	a bounds-spec-list, p(lb:) => a: only the lower bounds are given, and the pointer has the extents of the value.
PointerBoundsRemapping	a bounds-remapping-list, p(lb:ub) => a: both bounds are given, and the pointer has the elements of the value in array element order.

返回值

None. An enumeration value is not evaluated.

描述

The form member of Associate. With a bounds-spec the pointer keeps the shape and the strides of the value, so the upper bound of dimension i is lb + size(value, i) - 1 and is not stored; with a bounds-remapping-list it takes the elements of the value in array element order, which is why that value has rank one or is simply contiguous.
