This is the latest in a line of sixteen books written by Bruce Smith on
computing. He is at present the technical editor of Acorn User magazine,
and most of his books most have been on aspects of the BBC Micro.
This book is not for a beginner, and should only be considered for
purchase by someone with a good working knowledge of assembly language
programming, as the book deals with interpreters and compilers for use
with the BBC.
The book deals with the understanding and construction of the main
computer's routines, languages and the like, such as the BASIC ROM, LOGO
etc. The book attempts to be a practical course as well as giving lots of
theory. Each chapter of the book contains programs for you to type in and
try out, and on this point I would recommend you buy the disc which is
available additionally, as all the programs are in assembler and a few are
very long and involved. The disc costs `7.95.
The first two chapters of the book deal with "The Wedge" - the mechanism
in the BBC operating system which allows 'operations' to be intercepted -
and Interpreters - what they are, how they work and how to adapt them.
These chapters include an interpreter for you to type in and try out.
The first section on interpreters ends with a chapter containing an
interpreted Graphics language called "Grafrite" - the aim of this language
being that once you have worked through the chapter, you can adapt and
extend the language with the help contained in later chapters of the book.
The next section is about Threaded Interpreted languages (TIL) - what they
are and how they work. There are two examples included - "miniTHORF" and
"MiniTIL". There are detailed notes on how to use or expand these
routines, as well as how the TIL makes use of the stack (including two
examples).

Mastering Interpreters & Compilers Brian Ardron
The last sections of the book are on Compilers. Such routines are used to
change BASIC programs to machine-code, thus reducing memory requirements
and increasing speed.
Chapter 10 gives hints on the writing of a compiler, and introduces, as an
example, a compiler called "Tactless". Chapter 11 is an extension of the
preceding chapter, outlining the "Tactless" compiler's Library. These
routines produce code which can be used on any BBC or Electron.
There follows an Editor program, with details of using the "Tactless"
Compiler and it's related programs. Once typed in, the compiler is put
into action by the command "COMPILE". This will trigger the translation,
ordering, interfacing of the library, and saving of the stand alone code
created.
The "Tactless" compiler is a "Two pass" compiler - the first pass
calculates addresses and stores them, and the second assigns the operands.
The Compiler can be used with the ROM filing system by creating a Sideways
ROM image from the files "Tact" and "Libcode", and then blowing this into
an Eprom.
This book is definitely not for the beginner, as some knowledge of
assembly language is needed. But anyone who has ventured further than
BASIC will find this book of great interest. The programs included are
good, especially the suit of programs called "Tactless", and throughout
the program, the content helps to guide you through what is a very
complicated area. I would strongly recommend that the purchase of this
book should include the software disc also, as the programs are long and
all in assembler language - errors creep in if you are anything but a very
good typist.
So if you have a good knowledge of assembler, this book is for you.
