Confusion on your part, I'm going to guess. :-)
What exactly are you trying to do? The array does NOT look like it
contains string variables. If it *did* contain string variables, you
could just write them out as strings. If you are trying to write the
strings out as hexadecimal numbers, then IDL has to convert them to
hexadecimals to write them. A number "b" doesn't make much sense in this
conversion process, so IDL does what I would do, gives up and goes gets
a beer. What would you do?
Cheers,
David
