Hi Ansley,
  
  I have checked by issuing set mode verify: always in my script
  
  set mode verify: always
  set region/x=65:97/y=5:33/l=1:120
  use file1.nc, file2.nc
  let ta_avg=ta[x=@ave,y=@ave]
  plot ta_avg[d=2] , ta_avg[d=1]
  go plot_swath poly/over/pal=gray/nolab ta_avg[d=2] , ta_avg[d=1]
  
  This generates following message: 
  .................
  ! argument check
  QUERY/IGNORE $1"<usage: yes? GO plot_swath polygon_command ylo yhi [xpts]"
   !-> QUERY/IGNORE poly/over/pal=gray/nolab

  The variable and grid information in the files: 
  
  yes? sh d
       currently SET data sets:
      1> file1.nc

      GRID GFL1
   name        axis               # pts    start                 end
   XAX66_98   LONGITUDE            33mr    65E                   97E
   YAX96_123  LATITUDE             28 r

  Is there a easy solution for this?
  
  Also I have send another query regarding saving detranded data using time stamp. Can you send solution on that as well..
  
  Thanks a lot.
