Thanks Mary and Rick for the long answer. I wish NCL had a End of Line
character like C & Perl, and braces for nesting statements. Is it too
hard to change or will it now be too late to make such a change?
I am confused when I dont see braces or some sort of nesting delimiter.
Indentation doesn't seem natural without braces. I may sound radical
here :)
