filesize = index? what is index?

Where/how is the variable FILENAME defined? I would also suggest you check the value of dIOResult after the OpenWrite to make sure it is 'no error'. From the robotc help file; "sFileName must be a valid NXT file name"

As far as I know, the NXT wants the filename to be something.DAT, and it will appear in the 'my files' menu on the NXT or in any remote file utility such as the 'robot->NXT brick->file management utility' in robotc.
