Ben,
not sure whether it adds anything but traffic on the newsgroup ;-),
but you could perhaps make use of my Str2Byte routine which you find
on
http://www.mpimet.mpg.de/~schultz.martin/idl/html/libmartin_ schultz.html#Routines_S
It converts string scalars or arrays to byte arrays with a fixed
length so you can put them into a binary file.
Cheers,
Martin
