HP 2000 BASIC help / TREK73

Hi.

Nice to know
these
listings have
been found.
The game
brings back
fond
memories.

The 2000
was the first
mini I
programmed
on, in
college.

I have read
all the
replies, and
no one has
suggested
what I am
about to
suggest,
so here it is:

In order to
do a really
good job of
sanity
checking, it
would help if
we could
see
the listings
to compare
with what
has-been/wil
l-be typed.
People will
want to
port it to
other close
version of
basic
(hp-eloquen
ce) or
BASICV on
the 3000,
and
a typo is
always a
problem with
languages
that dont
necessarily
declare
variables
before
assigning
things to it.

So, if you
had a way of
scanning the
listings and
making them
available on
your web
site,
that would
be a boon
to
everyone.
Assuming
the listings
are in good
enough
shape to
scan.

As well, you
could then
spread to
work around!

Just my 2
cents
worth...

Thanks

Michel Adam

This is the

I wondered
if it were
something
like

PRINTTAB(1
4)"... but
there are
TAB()s
elsewhere.
A control
character,

If cursor or
screen
control, are
they octal
or decimal
(I'd

decimal) and
is there a
table
anywhere?
