Appendix A – Character Set, Z80N Mnemonics and Control Codes

This is the complete ZX Spectrum Next / NextZXOS character set, with codes in decimal and hexadecimal, the character each code represents, as well as the control codes (shaded) together with their corresponding NextBASIC tokens, if any. Tokens that are shaded are specific to the ZX Spectrum Next and cannot be found in earlier ZX Spectrum models. As the codes are also Z80N machine code instructions, the right hand columns give the corresponding assembly language mnemonics. As you are probably aware if you understand these things, certain Z80N instructions are compounds starting with CBh or EDh; the two rightmost columns give you these. Note that ED instructions that are shaded, cannot be found in regular Z80 CPUs and are only native to Z80N, the variant of the Z80 CPU, found on the ZX Spectrum Next. Control codes are marked with UW if they refer to User Windows and SW if they refer to System Windows.
