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