[ncl-talk] NCL addfile memory leak in functions

Hi,
For better or worse, I am unable to duplicate this (with ncl v6.6.2). I
didn't have access to the two GPLOT scripts you load at the top of your
script, so I don't know what your function is doing. I cobbled up a simple
one like:
VAR = "UGRD_P0_L100_GLL0"
...
function foo(f)
begin
v = f->$VAR$
return v
end
...
v = foo(f)
...print memory stats...
delete([/f,v/])
...print memory stats...
So, I'm not sure what to recommend here. By chance, is there a lot of
string processing going on somewhere?
