This attribute controls whether coordinate
values are reported whenever a Mapping
is used to transform a set of points. If its value is
zero (the default), no report is made. However, if it is non-zero, the coordinates of each
point are reported (both before and after transformation) by writing them to standard
This attribute is provided as an aid to debugging, and to avoid having to report values explicitly

When applied to a compound Mapping (CmpMap), only
the Report attribute of the CmpMap, and not those of its component Mappings, is used.
Coordinate information is never reported for the component Mappings individually, only for the
When applied to any Frame, the formatting capabilities of the
Frame (as provided by the AST_FORMAT
function) will be used to format the reported
When applied to any FrameSet, the formatting capabilities of the base
and current Frames will be used (as above) to individually format the input and output
coordinates, as appropriate. The Report attribute of a FrameSet is not itself affected by selecting a
new base or current Frame, but the resulting formatting capabilities may be.
