Advanced Electron machine code techniques

the long version

*How To Get The Best From The Electron!* Machine code programming is the key to achieving stunning effects, really high speed, and extending the memory capacity of your micro to cope with complex tasks. This book sets out a detailed treatment of the 6502 instruction set, addressing modes and the use of vectors. Multi-byte handling, direct screen addressing and exploiting the resident operating system routines are discussed in depth with particular application to graphics. Macros and conditional assembly are also treated. A number of fast sorting routines (called from BASIC) are described, capable of handling integers, floating point and strings within single and two-dimensional arrays. Many examples are provided, not only to illustrate the techniques, but also to put to practical use. These include ultra-fast machine code programs for alphabetical and numerical filing and indexing; smooth flickerless animation effects; and many others which will delight you. *The Authors* A. P.
