I have a couple questions regarding the 128's memory locations.  What is
the 128's equivalent of the 64's POKE808,234 (disable RUN/STOP-RESTORE),
and SYS64738 (cold-start routine)?  Also, I doubt it can be done, but is
there any way to read the numeric keypad in 64 mode?

Thanks for the information.  That's exactly, (and more than) what I was
looking for.  I sure know where to raise any questions I might have.  You

Hi Pax, (Pax Regal - Messa Olge #4).  I was looking at the list you provided
and noticed  "Auto-boot disk - sys65363".  How do I use that?  What is the
syntax required?  I tried entering SYS65363 and got a strange prompt line
that seems to act a little weird.  When I hit return, the cursor stays
in place, but the next character I type replaces the one just before the
cursor.  Am I doing something wrong?

Finner:  Hmmm...I just report 'em, I dont use 'em.
Seriously tho, I'm not much of a programmer, and havent
used the 'auto-boot disk' SYS.  Ill give it a shot tonite
to see what it looks like.  Maybe someone else out there
can help shed light on this one<?>

  I have typed up a file (chart) in 80 columns (on Wordstar),
which shows all the BASIC V7.0 Tokens/Keywords/Addresses.
If anyone is interested, let me know and i can upload it.
(There are a total of 171 tokens).

Mike....
   
   File #28 in the Software Library is already the Token list, unless this
earlier version has some errors in it, I'd hate to have a duplicate file
in there...!

Another question.........
  I know the Commodore 128 keyboard buffer is located from 512-576, but
where do you poke the value to tell the computer how many bytes are
currently in the buffer (the 64 location is 198)?

The location you are looking for, NDX, is $D0 on the 128...

I already found that in a 128 memory map today, but I can't seem to
get it to work.  I entered:
  POKE512,ASC("R"):POKE513,ASC("U"):POKE514,ASC("N"):POKE515,13:POKE208,4
I tried that a few times and always got a different response but not
the response I was looking for.  What am I doing wrong?

Ah HAH! Wrong buffer - you managed your way into the basic input buffer where
basic program lines are manipulated and INPUT can do its thing...
 
You WANT the KEYBOARD buffer at $034A...

GAds, thanks, Steve, <<Wow, that was an obvious one, too>>  Keyboard buffer
is only 10 bytes long...!

I thought that seemed a bit long!  So... How do I use the keyboard
buffer at $034A?  Is that the actuall starting point for the buffer
or the byte that tells how many chars are in it?

     Tom Sawyer

P.S.  *DEB*---  I didn't get anything when I tried it (manual control).

From within the program, poke the ascii codes for whatever you want the
program to do into the buffer at $034A, 034B, etc. Then poke NDEX to
keyboard buffer (that other location you already know) with the number of
bytes you left in the buffer.

When you exit the program and go back to direct mode, the computer will
seem to type the bytes you stored previously.
 
This method does nothing in direct mode except create, at best, garbage
and cannot be tested in direct mode.

This method also works if you want to pass things from within a program,
say, you had a terminal program and were in machine language and pressed a 
certain key to tell it to download. The ML could poke, say, a "d" into the 
buffer, set NDEX to 1, exit the ML immediately to end back up at a menu
which might have a GET in basic which would retrieve the stored "d" and
proceed to do whatever "d" was supposed to do. Tacky, but one way of 
interfacing basic and ML.
 
Hope this is of some help.

Hi!
A little direct mode one liner in native C128 mode:

SYS 32800,123,45,6  <RETURN>

I won't spoil the fun by telling you what happens. Yes, the
SYS format is strange but do it exactly like I've told you.
Also, there is an unimplemented command: OFF
Try it and see the error message you get. I wonder what they
had in mind for that command?

Some good tips from Bill Brier:
POKE808,112      Disable the STOP key
POKE808,110      Enable the STOP key
SYS65366         Software cold reset
SYS65363         Auto-Boot disk (just like powering up)
SYS65357         Go to C 64 mode (is non-reversible)
SYS65375         Toggle between 40 & 80 column screen
SYS65520,,R,C,0  Position cursor to row R & column C
    
Useful window commands:
SYS49474         Clear area inside window
SYS49482         Home cursor inside window 
C-128 INTERNALS (Abacus) says that the Run-stop/Restore can be disabled with:
  POKE 808,112:POKE792,98
To restore:  Poke 792,64:Poke808,110
    

If you are running your C 128 in 64 mode and you need to speed up the program
that is running, you can use the following sequence:

POKE53265,PEEK(53265)AND239:POKE53296,1

This switches the machine to 2 Mhz mode, essentially doubling the processor
rate.  Unfortunately, the 40 column screen will be blank during this speed
increase.  However, if your program is doing a long sort or number crunch, the
speed is worth having a blank screen.

To restore everything back to where it usta be:

POKE53296,0:POKE53265,PEEK(53265)OR16
  *Enjoy*
