1. creobj type=NDF dims=0 object=file This will create an empty HDS file. The top level structure is of type "NDF", which has little consequence. 2. creobj type=ARRAY dims=0 object=file.DATA_ARRAY This will create the scalar structure DATA_ARRAY in the top level structure of the file "file". The structure type is "ARRAY", which has special meaning in the Starlink Data Format. 3. creobj type=_REAL dims=[20,30] object=file.DATA_ARRAY.DATA This will create a two-dimensional array of _REAL numbers called DATA and situeated in file.DATA_ARRAY. The size of the new array is 20 by 30 numbers. 4. creobj type=AXIS dims=2 object=file.AXIS This will create a one-dimensional array of AXIS structures called AXIS and situated underneath the top level of "file".
