[gradsusr] Script Problems

[Stephen McMillan]

Andrew,
Is it critical to have the resulting defined field as integers?  If not, you
could do something like this, if your GrADS has the "if" conditional UDF
(such as in the opengrads version):

'define MinCAPE=1.4*hgt0deg-5400'
'define MinCAPE=if(MinCAPE,<,200,200,MinCAPE)'

Then, when you display MinCAPE, all areas < 200 from first define should
show up as 200.
