Seeing as you are still trying to use ENVI_FILE_QUERY, i suggest you ditch the call to openr, which is meant for access to a file on disk. ENVI_FILE_QUERY uses an fid to track files, and this is what you need to pass to ENVI_FILE_QUERY, not the file allocation unit.

If you want ENVI to open the file and then you can pass around the fid to all sorts of ENVI_DO_IT routines, then use ENVI_OPEN_DATA_FILE with the /TIFF keyword set for ENVI to automatically open the TIFF file. ENVI will internally keep track of the fid and you just pass around the fid to all sorts of ENVI related functions and procedures.

Cheers
Josh
