Re: How to work with lists?

Hi Sebastian,

NCL's facilities for working with the list type are rudimentary and
undocumented.
There are functions NewList, ListPush, and ListPop:

ncl 0> l = NewList("join")
ncl 1> ListPush(l,"a string")
ncl 2> i = (/20,30,40/)
ncl 3> ListPush(l,i)
ncl 4> x = ListPop(l)
ncl 5> print(x)

Variable: x
Type: string
Total Size: 4 bytes
             1 values
Number of Dimensions: 1
Dimensions and sizes: [1]
Coordinates:
(0) a string

The current version of NCL does not give any useful information if you
try to print the contents of a list, and there is no function to
return the number of elements in the list. We are currently working on
some enhancements for the list type to make it more functional.
