- C
- C Test program: tests speed writing float data in three ways:
- C
- C 1. to HDF SDS, default conversion
- C 2. to HDF SDS, no conversion
- C 3. to raw file, no conversion
- C
- C Note: in DFSDsettype routine, parameter #3 (DFNTF_CRAY), should
- C be replaced when using other machines. Currently, the
- C only allowable replacement is 0. (July 1990)
- C
- C
- C Input files: None. The data is generated by the program.
- C Output files: Three files, named by the user on the command line.
