HDF files

[Andreea Ira]

Hi all,
I have upgraded GrADS and even if I have now version
1.9 the "dtype hdfsds", like Jennifer said, it's still
not working and i wonder why.
The message i receive is :
Scanning description file:  testit.ddf
Open Error:  Can't open description file
I didn't replace the old version, i have both versions
now. Do you think that it might be a problem?
I appreciate any answer you might have. I am new in
this GrADS thing and i try to learn as much and as
fast as I can.
Thank you,
Andreea
