WIBBLE

by Andrew Paine



I bet if you tried to count the number of times you've sat staring at

your Speccy screen and thought "I wish I could make it wibble about a

bit" you'd run out of fingers and toes in no time at all. Frustrating,

isn't it? Andrew Paine has obviously encountered this problem more

often than most, because he's actually got up and done something about

it. Wibble is the result, and it does in fact make your screen, or

just parts of it if you want, wibble about a bit.



To put the thing into operation, type in the Basic section and save it

with SAVE "WIBDEMO" LINE 190. Then, by way of the Hexloader, type in

the Hex at address 60000 and save it after the Basic. Then reload and

run. Wibbly, eh?



But it doesn't stop there. You can tweak the program to your

satisfaction by POKEing the following addresses:



60004	Number of repeats until picture is stationary.

60006	Number of frames per repeat(must be a multiple of 16).

60119	Shift coefficient (how far it wibbles).

65533	Address at top left hand corner of window.

65534	Width of window in characters (allow at least three characters

	on either side of your image).

65535	Height of window (in pixels).
