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?

Still learning all the details on how things work.

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.
