Trace object path
Trace the path of an object and return the fully resolved name
as a text string.
CALL HDS_TRACE( LOC, NLEV, PATH, FILE, STATUS )
DAT__SZLOC ) (Given)
NLEV = INTEGER (Returned)
Number of path levels.
Object path name within container file.
FILE = CHARACTER
Container file name.
STATUS = INTEGER (Given and Returned)
The path name is constructed as a sequence of “node” specifications thus:
node.node......node.object such as: NGC1365.SKYPOS.RA.MINUTES where MINUTES is the name of
the object associated with the specified locator and NGC1365 is the top-level object in the
structure. If any of the nodes are non-scalar the appropriate subscript expression is included
thus: AAO.OBS(6).IMAGE_DATA If the bottom-level object is a slice or cell of an array, the
appropriate subscript expression is appended thus: M87.MAP(100:412,200:312) or CENA(3,2)
