[gradsusr] If else statement in grads

[Jayakrishnan P.R]

Dear Users,
             I have to compute the drag coefficient from Large and Pond
equation using grads.  My main concern is that does if else statement
effective in grads. Otherwise I will have to write a FORTRAN program and
write the outputs and read using grads. Kindly clarify this.
I have to do like this
Equation-1
if 3<=u<=6
and Equation-2
if 6<=u<=26.
My version of grads is Grads 2.0.1 in Fedora core-18.
