When you request a latitude or longitude that does not exactly match the center of a grid point, it sets the dimension to the lat/lon closest to your request. The message it returns is to let you know what that lat/lon actually is. <br><br><blockquote type="cite"><br></blockquote><blockquote type="cite">After this, I gave the command ?d z? and received back an ?Invalid Operand? notice that ?z not a variable or function name.?<br></blockquote>If you issue a 'q file' command, GrADS will show you the list of variables in your file.
