   As  source   file  for  translation  is  a usual text file, for  which 
 equitable following rates of the writing:

    1) all  unadulterated mnemonics must be written together,assembler 
       does not make differences between  title and small letter of the
       alphabet, so mnemonics 

               'ADD' 'AdD' 'ADd' 'Add' 'aDD'

       are identical and assembler do not differ them;

    2) between   separate  mnemonics,  digital constant, mark,  correspo-
       ndence and   comments  can be  pleaced  many insignificant  symbol 
       and  controlling  sign,  such  as  gap, tabulation,   return   the  
       carriage, linefeed  etc.,there are no restrictions on accomodation  
       of the commands in text is not  imposed;  this  allows  programmer  
       an enough liberally to pertain to text of programm with standpoint 
       of its exterior; 

    3) follows  to  point  to  the  fact,  that  assembler  supports  the
       higher  part  of   the   table   symbol   ASCII,   in   which   is 
       enclosed    national    alphabet,  but  all  standard   mnemonics, 
       provided    in   a   ⁿ1   table-addon   of   reserved   mnemonics, 
       was  translated   for  latin  alphabet,  and  so  necessary neatly 
       to    pertain  a   wadding  of  mnemonics,   that   have   in  its 
       composition   symbols,  which  are   equally  writed,  but  having 
       differ   coding.   However,   given   rule   does   not  mean that 
       programmer    must    avoid    the   national   alphabet,   except 
       for   writing   explaining   commentaries  that  is complitly seen 
       in   such  programming   languages,   which   were   are  oriented 
       only   on   english   user.  By  help   of   the labels structures 
       and   correspondence   the   user  can  in  any   place   of   its 
       source   file  assign  comprehensible   for   him  indication  and 
       use it with standard mnemonics of the language.  
       So such, for instance, command, as 

                       Sum up operand1,  operand2;

       will  not  contain  mistake and it is will be translated correctly 
       under  that  condition  that  all provided in example of mnemonics 
       will beforehand described.   

    4) the main file must be ended of the microprocessor command, that is 
       concluded in quotation marks.

   Strictly   keeping   rules  of  commands  writing, the neatness in set 
 of the text of the program  will  guarantee  the  quick  translation and 
 debug - the  practice  is  witnesses that majority error appears firstly 
 of all because  stile of writing  is careless  and the inexact knowledge 
 of the development object.
