Unless every line is linked this way, you're still being slowed down,
albeit trivially, to process the link.  If every line _is_ linked this
way, you're being slowed down as if every line is separated by a comment
whether it is or not.  Whether this is a good or bad thing is probably
open to debate (isn't everything?).

No, every line contains a link to the next executable statement.
So if LET statement 10 is followed by REM (comment) lines 20,
30, and 40, and LET statement 50, the link in line 10 points
to line 50.

A lot of trouble, but we wanted to make very sure that no one
had any excuses not to use comments.

The discussion about cards reminds me of a tale told by a lecturer at
Cambridge.  He had worked for IBM at some point (and was the most vocal
anti-IBM faculty member).  Anyway, a favorite theme of his was IBM's
staunch efforts at co-operation with the rest of the industry in producing
universal standards :-).  Once he said that they were in the midst of
standards negotiations on cards when they broke off the talks to introduce
the 96-column punched card.

I have never heard corroboration of this.  Anyone got more info?

A good and worthy cause.  I like it (for whatever that's worth).  BASIC
programs generally need all the commenting they can get (and usually more
than they do get).

No it's not!

It's obviously late, and I'm tired. But aren't we all?
