Re: reading a lot of variables

Hi Ahmed,
When you get a subscript out of range statement, it usually refers to an
instance where you are calling for an index number that is beyond the
range of your array.

For instance, if you did this:
*var1=new(72,"string")*
*do i=1,72*
*var1(i)="EVAPORAT_GDS0_SFC_acc"+i+"h"*
*lsp = wrf->$var1(i)$
print("Now done with i = "+i)
*
*end do

*That would result in an error message when NCL tries to access
var1(72), as var1 is of size 72 with indices ranging from var1(0) to
var1(71). (NCL is a 0-based indexing language.)
Hope that helps.. Adam
