         Multi-Coloured Border

There are some strange and wonderful things that can be done with the screen on
the Spectrum. This program from Richard Couchmam of St.Ives in Cambridgeshire shows
how you can display a multi-coloured border. This is useful when a program stops
and you want the person using the machine to input something.

The program that plays around with the character set is very strange. If
anyone can think of a use for it we will be pleased to hear from you.

I HAVE written a program which allows the Spectrum to show a multi-coloured
border display (normally one colour can be displayed at once with the
Spectrum's border). This is the program used:

   1 BORDER 1
   2 REM Your Writing Here
 333 BORDER 1
 444 BORDER 2
 500 BORDER 3
 600 BORDER 4
 700 BORDER 5
 800 BORDER 6
 900 BORDER 0
1000 BORDER 1
1100 PAUSE 1
1200 GO TO 333

Try this program:

10 BORDER 2
20 BORDER 3
30 GO TO 10

The strange thing about this program is this: Press SPACE and it will speed
up, and it hasn't got any pause statements in. Press '0' and 'P' at the same
time and it will slow down. Press '0', 'P' and 'I' and it will stop. Press
'E' and '0' and 'P' and 'I' and it will go backwards.

Try this:- POKE 23607,8. This will move the character set back by 1. POKE
23606,X. IF X=8 the character will be moved back 1 pixel. If X=16 the
character set will be set back by 2. If X=24 the character will be set back
by 3, adding 8 to X sets the character back 1 more. Try this by doing this
program:

10 FOR a=0 TO 255
20 PRINT AT 0,0;"a"
22 POKE 23606,a
25 PAUSE 10
30 NEXT a

         Weird & Wonderful Patterns
    from Computer Choice, January 1984

THESE two incredibly short programs form the nucleus of an entire set of
similar programs, all of which produce weird and wonderful spirographic-like
patterns on the screen of the Spectrum. They are meant to be experimented
with as a lot more can be done. For example, if you try changing the number
by which PI is multiplied in lines 22 and 25 of program one, you will start
to get different effects.

         Flashing Border
      by W.R. Billany
    from Computer Choice, January 1984

Here is a short program using the now famous OUT 254 trick on the Sinclair
Spectrum. It is written by W.R. Billany from Hull, and gives a flashing
border, which certainly draws attention to any text printed on the screen.
