Dear everyone,

  My friend asked me the following questions, but I could not answer.
I hope someone helps me.

  Question:
   There is a following ctl file. The data is global, starting from
-179.75 with 0.5 deg resolution.
   When the display command is issued, then GrADS says that the
display area is set to like,

LON set to 0 360
LAT set to ....
LEV set to ....
Time ..........

   The question is that the original ctl shows that the western
boundary of the data is from -179.75,
however, the display says GrADS changed the longitude, starting from
0. Do you know why?
