When you have run the program, look at the pieces by going into graphics mode. ### Alternative Character Sets As we are going to see in *Chapter 20 – Channels, Streams and Windows* the ZX Spectrum Next provides via its windowing system, the ability to display alternative character sets. In order to set up however an alternative character set, characters have to be defined somewhere in memory, very similarly to the way we did the chess pieces or the Σ symbol above. The characters redefined are limited to the **96** from code **32** until code **127** and should be in that order. A successive series of **768 POKE** statements incrementing the memory address by one location at the time, will define them and then a last **POKE** altering the
