global variables in procedures

Hi,

is it possible to have global variables in procedures? Sometimes it is useful for reducing code amounts but my experiences so far suggest that non-locally defined variables are not available at the calling level. Of course could load ncl script with this sort of code but it is safer to be able to (generally) locally define variables, as exists in procedures.

Thanks,
Mark.
