[gradsusr] Use of subwrd, sublin y substr in GrADS 2.0.a9

[Juan Jose Amides Figueroa Urbano]

Hi all, I'm working on GrADS to make some products WRF with temperature at 2
m but my problem is to place the date on the map, when using q time indeed I
can see the date such 06Z20DEC2010 to 06Z20DEC2010 Mon to Mon; I tried using
the command subwrd, substr and sublin but in doing so I get the following
error:

Syntax Error:  Invalid Operand
  'subwrd' not a variable or function name
  Error ocurred at column 1
DEFINE error:  Invalid expression.

Thanks.
