[gradsusr] If else statement in grads

[Jayakrishnan P.R]

I have tried the method as suggested by users. Still some errors. I
herewith attach the gs file I used for the computation. Could anyone point
out the errors.?

'reinit'
'sdfopen d:/Ekman_transport/uwnd.2009.nc'
'sdfopen d:/Ekman_transport/vwnd.2009.nc'
'set lev 1000'
'define W=mag(uwnd,vwnd.2)'
if(W>=3&W<=6);
define cd=(0.29+3.1/W+7.7/W**2)/1000;
endif
if(W>=6&W<=26);
define cd=(0.6+0.07*W);
endif
'define taux=1.3*cd*W*uwnd'
'define tauy=1.3*cd*W*vwnd.2'
'd cd'
'printim D:/Ekman_transport/cdrag1.jpg white'

Thnaking You.
