Blitz Basic 2.1 (CU-Amiga CD Demo)
==================================
About this demo
---------------
1) You cannot create stand alone executables with this demo version.
2) This demo contains some of the new features of Blitz Basic 2.1
New editor - Version 2.1a (OS2.1 menu problem fixed I hope)
New debugger - Version 2.1
Large Deflibs - Contains lots of new third party commands
The new editor/debugger only work with OS2.1 or better and because they
are quite large, you really need 2Mb of memory to compile large programs.
3) All the example source code (examples and games dirs) should have
runtime error checking on by default. Once you know a program runs
successfully, recompile it with runtime errs off (compiler menu/
compiler options).
4) To make sure Blitz has the right path to a programs data files, start
up Blitz by clicking on a source code icon instead of the Blitz2 icon.
5) Don't forget to use 'Right Amiga-Help' on the same line as a Blitz
command to bring up the on-line help, or 'Help' on its own to display
the command syntax in the screen title.

Demo Contents
-------------
Blitzlibs - A directory containg a few resident files, which some of
the examples may require.
Bums - Examples from the Blitz User Magazines 5-8. When you buy
Blitz Basic 2.1 you receive a registration card and the
chance to subscribe to BUM. The next issue is BUM 9 and
it should be available soon. It costs 5UKP for an issue
which usually consists of two disks that unpack onto four
disks. BUMs contain the latest fixes, libs, etc and lots
of examples.
Docs - Documentation for the Acid Blitz commands, the third party
library commands, the new editor and the new debugger.
Examples - Plenty of examples covering most of the Blitz commands. Just
double-click on one of the source code icons and away you
go. All the examples should have runtime error checking on
by default, so once a program runs correctly, recompile it
with runtime errs off (compiler menu/compiler options).
Games - Lots of executable games, most of them with source code.
Installing to Hard Disk
-----------------------
1) Make a new directory on your Hard Drive.
2) Copy the following files from the Blitz directory on the CD into
your new directory.
Blitzlibs <dir>
Acidlibs
Blitz2
Blitz2.info
Deflibs
Defaultdbug
Help
Help.dat
Ted
Ted.info
3) Copy ted.library from CUCD:Libs into your Workbench Libs directory.
4) Add the following to your startup-sequence or type it into a shell
before running Blitz.
Assign BLITZ2: <your hd>:<your new directory>
Assign BLITZLIBS: <your hd>:<your new directory>/blitzlibs
Thanks

Fingers for being so courteous and patient.
RWE/LES/RI for their very nice libs/docs.
Xbones for his protracker lib.
Tiffs, ><>, and all the others on the Blitz List.
Me for creating yet another Blitz demo.
Blitz Basic 2.1 Release Notes
=============================
1. Introduction
---------------
Welcome to Mark Sibly's BlitzBasic programming language. A powerful
integrated programming environment for all Amiga computers.
New to version 2.1:
- online help
- restructured library handling
- bug free parameter passing
- comprehensive AGA and 3.0 support
The main Blitz program disk has been put together so users programming
on 1 meg single floppy A500 systems can boot straight from the disk
and start programming immediately. Those with more powerful systems
should note that due to space restrictions the advanced debugger,
third party libraries and enhanced editor can be found on the extras
disk.
2. Up and Running
-----------------
A lot of reviews of Blitz have criticised it for being unstable. Most
often they have missed the fundamental concept of runtime errors that
Blitz uses to stop your program crashing during development.
When runtime errors are enabled from the compiler options, Blitz compiles
your program with checks on every command so it can't do the guru thing
and make us at Acid look bad. These checks however make your program bigger
and slower making us at Acid look bad anyway.
As we don't really care what we look like, we offer this advise; always
enable runtime errors until you are quite sure your program can not
fall over (bringing up the runtime error debugger). Once you are sure
it is bulletproof THEN disable error checking and let it fly. This also
applies to official Acid demos as wrong directories and unfound files
may cause errors also.
3. Online Help
--------------
Previous versions of Blitz incorporated a simple syntax help system
whereby pressing the Help key when the cursor was on a Blitz command
would print the syntax of that command on the title bar.
Blitz2.1 now sports a full online reference manual, simply use the Right
Amiga/Help keyboard combination to invoke the Blitz online help software.
4. Library handling
-------------------
BlitzBASIC commands are loaded by the program from several sources:
acidlibs - a single file containing standard Blitz commands
deflibs - commands compiled from third party libs found in blitzlibs:
userlibs - all libs found in directories branching off blitz2:userlibs
The reason for this change is to make it easier for Acid Software to
distribute libs in the future. Users who build up a collection of third
party libraries in their deflibs file will be able to upgrade their
acidlibs without reconstructing their entire blitzlibs: volume.
Those developers creating their own libraries can now use the userlibs
drawer to hold beta versions of their compiled libs allowing for much
faster reloading of libs during development.
