How to suppress the warning info "entire grid undefined" in GrADS

[Rafael Rosolem]

if  understood correctly what you have meant, you should try to open any
ctl file you have, then select the lat and lon ranges you desire and
type draw map. it worked for me.

'open file.ctl'
'set lat -90 90'
'set lon -180 180'
'draw map'

I hope it works.
