[gradsusr] gradsusr Digest, Vol 16, Issue 50

[rajuattada]

Dear all,         Whenever i am posting queries to grads users (for help), my actual message is not displaying properly.         What may be the problem ??


*******************************************Message displaying like this way*********************************

Dear all,
          I want to do regrid from my actual data.
          I have done in two ways.
          First i used,      re command. it is showing following error.
 
                                                d re(rf,0.405,0.405,bs)
--------->> where rf is variable and 0.405 is my resolution
                                               Syntax Error:  Invalid Operand 
  '                                            re' not a variable or function name
                                               Error ocurred at column 1
                                                DISPLAY error:  Invalid expression 
                                                 Expression = re(rf,0.405,0.405,bs)
   In otherway,              d regrid2(rf,0.405)
                                Syntax Error:  Invalid Operand 
                              'regrid2' not a variable or function name
                                  Error ocurred at column 1
                                DISPLAY error:  Invalid expression 
                              Expression = regrid2(rf,0.405)
