VMS Platforms

The and command file may be used to build the FITSIO library on DEC Alpha/OSF and VAX/VMS machines (e.g., type `@makevmv' on the command line). Note that the vmsieeed.mar macro routine is used on VAX/VMS systems to perform the translations between Vax floating point formats and IEEE floating point formats.

FITSIO supports both the G_float (default) and D_float compiler options on Alpha VMS systems. The vmsieee.c routines perform the the IEEE translations on Alpha VMS machines when the /float=D_float compiler option is invoked. Th file can be used to build FITSIO with this option.
