Regrid2 error

[Kanhu Charan Pattnayak]

Dear Grads Users
I am trying to interpolate IMD 1deg gridded data to 0.5deg in *Grads-1.8sl11
* in my AIX Unix Platform and we are having
I got the following message.

ga-> define newg=regrid2(rf,0.5)
Syntax Error:  Invalid Operand
  'regrid2' not a variable or function name
  Error ocurred at column 1
DEFINE error:  Invalid expression.


But  I don't know why this error is coming.
I have already checked that Regrid2 is there in the GrADS directory.
Please suggest me what to do.
Thanks in Advance.
