This application converts an HDS object (or structure) so that
all primitive data values within it are represented using the
appropriate native data representation for the machine in use
(this includes the appropriate number format and byte ordering).
This may typically be required after moving HDS files from
another machine which uses a different number format and/or byte
order, and will minimise the subsequent access time on the new
machine. Conversion is performed by modifying the data in situ.
No separate output file is produced.
This application can also be used to replace any IEEE floating-point
NaN or Inf values in an HDS object with the appropriate Starlink
bad value. This conversion is performed even if the data values
within the object are already represented using the appropriate
native data representation for the machine in use.
