The biggest thing for me is that John doesn't seem to think there's
a major conceptual problem with inserting C code into DCL, even
given DCL's unique requirements.

If you can get C code into DCL, I wonder if that could be used to
fix up other DCL issues.

For example, we know from previous discussions the line editing code
in the terminal driver is an unmaintainable mess, so we can't edit
command lines which are longer than the terminal width. Could the problem
be worked around (at least for DCL) by placing line editing code into
DCL ?

This could also bring along other benefits such as a much nicer history
searching method, including incremental search.

Simon.
