[gradsusr] Is it necessary to install perl to Read Grib2 with GrADS?

[Bo Zhang]

Hi all dear Grads users,

I am trying to use GrADS 2.0.a9 to interpret Grib2 data on a linux machine. First, I don't have grab2map in my package which seems essential to create a ctl file. Second, another potential option is by using g2ctl. If I am understanding correct this would need perl, which I don't have the privilege to install on the server.(I assume it won't work If I just install it under my home directory. Correct me if I am wrong.) Is there a way to Read Grib2 with GrADS? On GrADS, it sounds like a build-in function for the newest version. Grab2scan does work, and here is what it displays.
