I would like to use ENVI_OUTPUT_TO_EXTERNAL_FORMAT to save some ENVI files into various formats (ESRI GRID and tiff). See below for the code I am using. I keep getting an error on my endfor and end, not sure what I am doing. Thanks pro outputtoexternalfile2 compile_opt strictarr  ENVI, /RESTORE_BASE_SAVE_FILES ;set up path to input and output files input_path = 'E:\test\'     ; search for data files in the specified directory     files = FILE_SEARCH(input_path+'*_NBR', count=count)     IF (count EQ 0) THEN BEGIN   PrintF, 'No files were found to process'  ENDIF ;open file    for i=0, count-1 do begin     ENVI_OPEN_FILE, files[i], r_fid=refl_fid      if (refl_fid eq -1) then begin       envi_batch_exit       return      endif ENVI_FILE_QUERY, refl_fid, ns=ns, nl=nl, nb=nb, data_type=data_type, fname=filename    pos=lindgen(nb)    dims=[-1L,0, ns-1, 0, nl-1] out_name = filename + '_test' ENVI_OUTPUT_TO_EXTERNAL_FORMAT, dims = dims, /TIFF, FID=refl_FID, pos=pos, out_name=out_name $ endfor end
