Reading binary double floats from an old data file

I am learning LV and I have been trying to write a routine to read and
display an old binary data file as a tutorial. The file was written in C in
a MS DOS program. I can get all the integer and string data from the header
but I am stuck with the double precision float values. The integers have to
be byte swapped (no problem) but the dfs are not cooperating. I tried
flattening them and rotating the string, etc. Converting from big-endian to
little-endian was easy in C but I can't seem to come up with a LV way.
Any suggestions.

Thanks

I believe the procedure must also involve the "Swap Words" for Doubles.
