Hi again,

An additionnal comment on how to achieve this data count.
You can use the SPAWN:"command" inside a string array definition
but also use the SPAWN function.

I have noticed that their behaviour is not similar.
Here is a example:

yes? let a={spawn: "ls *.shp"}
yes? say `a,return=size`
2000
---> so use of @NGD is needed
yes? say `a[i=@ngd]`
4

yes? let a=spawn("ls *.shp")
yes? say `a,return=size`
4

For this reason, I prefer to use the SPAWN function as in the following 
example

yes? let listfiles=SPAWN("ls *.nc")
yes? repeat/name=N/range=1:`listfiles,return=size` ( \
...?       def sym N=`N` ;\
...?       list listfiles[i=($N)] ;\
...?       use "`listfiles[i=($N)]`";\
...? )

Patrick
