OK. I had to refresh my memory and make sure I was remembering the 203
error correctly. 203 is an input/output error. Generally, it means you are
attempting to operate in a file in a manner not consistent with the way you
opened or created it. Usually, it means you are attempting to write to a
read only file (:READ) or read from a write only file (:WRITE). If it isn't
a file, then you are operating on a module as input that should be output
or vice-versa.

I agree with what Curtis wrote. You should provide some code here that can
help us determine where the problem is occuring.
