[gradsusr] problem running the script skew.gs

[Glauber Mariano]

Hi Juan,

I think that your problem is about your lat/lon point that you select! When
I run the skew.gs I put some tests to know if my lat/lon is available on my
data, or if my data has undef values ex:

'd t'
testelimit = sublin(result,1)
testelimite = subwrd(testelimit,2)
if (testelimite = Request)
   say ''
   say 'There is not data in this point'
   say ''
   i=i+1
else
'set z 4'

*****UNDEF test *********** begin
'd t'
testeundef = sublin(result,1)
testeundef = subwrd(testeundef,4)
say ''
say 'This point  'i' has 'testeundef
say ''
If (testeundef = 0)
   i=i+1
else
*****UNDEF test *********** end

....... rest of the script

I hope that you can run it now...
