[gradsusr] regrid data

[Jackie Yip]

Hi Subash,

I also got the error
"Syntax Error:  Invalid Operand 're' not a variable or function name"
even though I used GrADs 2.0.a9.oga.1.

Is the re function an extra thing one must install like a user define
extension? Or is the re function built-in for GrADs 2.0.a9.oga.1.?

Thanks

Zheng
