What does the last line do?
I mean Calll &4000 will eventually run into the variables of basic and then crash ... was there any comment of this in the magazine?
That'll be because it's expecting Listing 2 to have been loaded beforehand.

When Listing 3 has displayed the "CPC iNTERNATIONAL SCREEN" that's it - nothing else happens until I touch a key and then the CPC resets.
Doing something wrong?

Dove into the magazine this came from and realised I had it the wrong way around - listing 3 draws the test screen for all the listings *after* it (i.e. 4 to 9). So you run listing 5 (say) to load it's effect to &4000, then listing 3 to test it.

Understood, thanks :)
Pressing the spacebar (maybe any key?) generates the effect.
