Introduction
------------
Back in 1985, the first Amiga 1000 computers came with Metacomco's ABasiC
language. Unfortunately ABasiC does not work under Kickstart 2.0 (V36) and
later; this patch fixes the problem.

ABasiC is hard-coded to use the default NTSC screen height (200 lines). While
it works fine on both NTSC and PAL Amigas, you can also patch ABasiC to use
256-line screens, so filling the whole PAL screen area.

With version 1.1 of the Amiga OS, ABasiC was replaced by Microsoft's
AmigaBASIC. ABasiC and AmigaBASIC are very different. ABasiC is a more
"traditional" environment than AmigaBASIC, and seems faster and less buggy.

Apart from historical interest, David Addison wrote some excellent games in
ABasiC which are available on early Fred Fish disks and Aminet. Now you can
take a virtual trip back to 1986 and play his versions of Klondike, Othello
and others! They are surprisingly good, considering they are written in BASIC
and run on a 256K machine.


Where to get ABasiC
-------------------
If you don't have ABasiC but would like to try it, it can be obtained from
Rainer Benda's web site at http://www.rbenda.de/commodore/software.html
(direct URL http://www.rbenda.de/commodore/_basic-1_0.dms).

Several archives which include ABasiC and various programs are available from
ftp.back2roots.org. At least these:

HELP WANTED!
------------
I have not tested the patched version of ABasiC extensively. Please let me
know if you encounter any problems.

Jim Cooper, formerly jamiesas.com, apparently developed a similar patch for
ABasiC a few years ago but never released it. Does anyone know his current
email address? He mentioned it in a posting to comp.sys.amiga.programmer in
1999:
