Re: Any short type-ins for unattended Beebs?

And to round off for now, here's one that switches screen modes periodically:

Code: Select all

10MODE2
20?&FE00=0
30M%=2
40A%=&18
50B%=0
60REPEAT
70!(&3000+RND(&4FFF))=RND
80?&FE03=A%
90A%=A%+1
100IF A%=&40 A%=&18
110B%=B%+1
120IF B%=256 B%=0:M%=M%+1:?&FE07=(M%AND7)*8
130UNTIL FALSE

Re: Any short type-ins for unattended Beebs?

This can probably be shortened but is a more colourful version of the previous program:

Code: Select all

10MODE5
20VDU23,1,0;0;0;0;
30A%=&18
40REPEAT
50!(&3000+RND(&4FFF))=RND
60?&FE03=A%
70A%=A%+1
80IF A%=&40 A%=&18
90UNTIL FALSE
Edit: Also try MODE 2 instead of MODE 5 for even more colours!

Ah, it turns out I had run some of the previous programs before running this one. Try the next iteration on this theme:

Code: Select all

10FOR A%=8 TO &20
20?&FE03=A%
25!(&1000+(RND AND &7FFF))=RND
30NEXT

Re: Any short type-ins for unattended Beebs?

One for the Electron. Perhaps someone can convert it to the Beeb:

Code: Select all

10FOR A%=8 TO &20
20?&FE03=A%
30NEXT
40RUN
&FE03 controls the top 6 bits of the screen start address.

It gives you two expansion interfaces for the price of one, especially since a lot of add-ons were made in cartridge form rather than use the bus directly.
