     Умерев  в Англии и на Западе в целом,
как это не парадоксально, в странах СНГ ZX
Spectrum-совместимые компьютеры переживают
бум.  Появление  поистине  проффесионально
написанных  программ,  в  первую  очередь,
игр, показывает, что это семейство компью-
теров еще имеет некоторыйpotential.      
                                          
The software market is gradually forming
ZX Spectrum-compatible framework
our computers. There is everything here: games, adventures,
good programs, programs of various
for service purposes.  Some of them
written well, many - poorly, only a few
prostrate - excellent. What are they written on? What
same from the tool support
our programmers use? In 99% of cases
tea is an assembler - from the good old
Hisoft GENS Assembler 4.1up to new ones
TASM, EDAS etc.                        
                                          
 We're used to assembler. Every try

Compiler, Hisoft Pascal, etc. finishing-
was a failure - the “quality” of these compilations
tors is amazing. In addition, high languages

voluminous code so that our programmers,
brought up in assembly language, could use it
agree. But assembly language programming --
this is not normal! Not on any model, not in
one class computer central
instrument is not ac-
sampler!  Its place is programming
tyre resource-intensive or time-intensive
sections of programs, drivers, etc. Even
if your program is really critical
in this sense, then (as statistics show
tick) this criticality is caused by 10% of the code:
they need to be written in assembly language.  But os-
The remaining 90% of the code can be written in sufficient
but in a high-level language!                 
                                          
 Considering all of the above, the author
The long-cherished idea has finally matured

lyator on ZX-Spectrum.                     
                                          
 It is assumed that the language will be
only low-level, which in terms of quality
Yes, it will be close to assembler, but sufficient
but abstract and machine-independent so that

was able to reduce the time it took to write my programs

times compared to assembler.           
 The language is designed as C-like,
but even more concise and optimal for
8-bit microcomputers. His level

knows "C--" is a C-like low-level

 The language will necessarily contain pro-

The topic of programming is not complete without
object level.  One of its advantages
are that the programmer can
create a library of programs for a specific
purpose and sell it as an object
th file and the external declaration file. like this
the library can be purchased and used for
programming, it is not possible to change, re-
dig, dig up, etc., as they really like
do our hackers. And all because

 The language will contain a set of libraries,
with which you can implement
anything from including music in the program

exceptions will be supported from multi-level
