A record that bundles together a process dimension, a coordinate, a template subscript, and any shell subscripts implied by a particular global subscript value in a particular range.
The interface of the Location struct is
struct Location : public Coord {
int tem ;
int sub ;
int blk ;
} ;
The Location record does not include the global subscript itself. This means that a Location record constructed from a subrange is identical to a Location record representing the aligned element of the parent range, although global subscript relative to the two ranges are generally different.
