I note that this violates the instructions. Dr. Grace Murray Hopper would
love this;
although I understand her desire for English language style languages:
I fundamentally disagree with COBOL the idea that COBOL is one of them,
and absolutely agree with Dr. KEI''s usage of _natural_language_ as the
basis for J,
as well as the attitudes, and more importantly, philosophy of the
resulting community of
language designers, users, and experimenters
not the least of which being RH, and his quietly reflective Socratic
method of teaching newbies.
Thanx, Dan: you bring the focus back on a seminal point of the underlying
_athema_ that makes J work:
thinking first.
