The time: 18:56:33 on Jan 25 1991, Roundtable is on on Radio 1
and in about twenty five minutes I am going to go and watch
A.W.O.L starring Jean Claude Van Damme, I've just about got
time to start this article for the THB's disc mag STOS Bits.
Six months ago Eddie (from the THB's) agreed to draw some
graphics for a program I was writing called 'Early Learning
Maths' on condition that I gave him some routines for his disc
mag. Well I got my graphics five and a half months ago and due
to unforseen circumstances ( an operation, an AMIGA, a broken
ST, and several assignments ) Eddie did not recieve his
routines. Until now that is. I got my ST back from the computer
doctors yesterday and am in the process of compiling some
routines.
( ASIDE: Pet hate number 72, ST repair companies. When my ST
died I took it along to a local repair company who promptly
decided that I needed a new power supply unit. Cost, about
£100. Unable to afford this I gave my computer to a
technician here at Keele University, who repaired it in 24
hours at a cost of £18, £14 for parts and £4 for labour.
My ST didn't need a new PSU. Conclude what you will !!!!! )
Anyway, back to the routines. I have written two short
programs. The first is inspired by Eddie's article on rasters
in STOS ( STOS Bits issue 1 ) and is relatively simple, but
looks quite good. The second is a program which demonstrates
several routines: a menu shell, a keyboard/mouse input routine,
and several 'appear' routines.
.... 7.23 gotta go, I'll be back in about three hours,
maybe I'll tell you what the film was like, maybe not ....
.... 7.25 Oops, forgot my ticket 0....................
....11.04 crap film, now shall I watch THE WORD or
continue typing this shitty text file? No contest, see you in
fifty four minutes ........................................
.... 12.04, 28/1/91, So it's taken me two and a half
days to get back to this, who cares?
Where was I? Right, describing the routines to you.
The raster routine is very simple, but includes moving rasters.
The actual routine to do the rasters is line 80 onwards and
works by waiting for a VBL and then changing the background
colour as quickly as possible. By the way, don't compile it (
timing gets a little fucked up, and you get a REALLY messy
display!! ).
I think all the routines in the other program are fairly well
documented so I will not say anything else about them. ( Except
that you move the menu bar with the cursor keys, and select an
option by pressing return. ) One other thing here are some line
numbers for you:
1-200 : main program
4000-4999 ; appear routines
5000-6000 : menu shell
10000-10100 : mouse/keyboard input routine
That's all you are getting, goodbye ... for ever (possibly).

The two sources are called RASTER4 and MENU and can be found in
the PROGRAMM folder.
