MAKCOOKY.PRG


                          Mike Horwell 14/4/91



As some of you are aware, the STE and TT have a 'COOKIE JAR' installed.
This COOKIE JAR is a table which is set up by the operating system with
the capability of informing applications the type of system they are 
running on - such as machine type, processor type etc.

The really neat thing about it is that any new devices installed can
insert their I.D and address (or version number) so that other 
applications can take advantage of them. For example, MACCEL.PRG v2 
and v3 install an I.D of $00AA006E followed by the address at which
MACCEL is loaded. If you wanted to configure it yourself, think of how
difficult it would be to find it if you couldn't use this table.

OK - so now we know how useful this table is, what about the ST owners
who do not have this table? Never fear - that's exactly what MAKCOOKY
does. It checks the location at $5A0 to see if a table is already 
installed - if so it simply exits. If this location is empty, it will
set up a new table.

**********************************************************************
NOTE

Since the program is installing the cookie jar, the machine MUST be a
ST and so the program makes some standard assumptions regarding the
machine, video shifter type and sound capabilities - but does make an
attempt to identify the type of processor installed in the machine by 
using some commands only recognised by the different processors. 

**********************************************************************

The variables installed are :

	_CPU	This is the type of processor
			$00000000	= 68000
			$00000014	= 68020
			$0000001E	= 68030

	_MCH	The type of machine
			$00000000	= ST
			$00010000	= STE
			$00020000	= TT030

	_VDO	The type of video shifter
			$00000000	= ST

	_SND	The type of sound output
			$00000001	= ST Sound Chip

There is also space for 8 more COOKIES 


Well that's it, except to say that this program is in the Public Domain
