Ben, did you try using the OPEN keywords /BINARY and /NOAUTOMODE in
Windows (I believe these keywords are no longer required in IDL 5.4).

BINWRITE and BINREAD are designed for this sort of thing. If you want to
include a string, convert it to BYTE type before writing it, and then
convert back to STRING type after reading it.
Of course if you want to go full steam on this, you may want to consider
netCDF or HDF.
