[gradsusr] possible bug in define mode

[afzaalkarori]

  Dear Stefano

Redefine u-component separately. something like
-> wind = skip(uw,8,8) 
then plot
-> d wind;vw
It should work
Good Luck!

Hi everyone,
I am using Grads 2.0.0.oga.1 and I am facing an odd issue.
When I try to define an expression for plotting wind vectors in this way:
define wind=skip(uw,8,8);vw
(where uw and vw are the two horizontal components), I get the following 
error:
Syntax error: expected operator or ')'
Error occurred at column 23
Grads displays wind arrows in a proper way, instead, when I plot the 
expression directly:
d skip(uw,8,8);vw
Bets regards,
Stefano Materia
