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.
