 HS_FMODE
        Determine floating point types of an HSIO file

 Usage:
        fmode = hs_fmode(unit, iswap)

 Return Value:
        fmode   byte    0 = Native data, 2 = IEEE data (swapped or on
                        non IEEE platform), 4 = VMS data, 8 = byte
                        data.

 Arguments:
        unit    long    The unit on which the file is open.
