9. Command of the loading  of the LOAD register.
                  ══════════════════════════════════════════

   The  given command differs from all other commands of accembler, because it
assigns the loading of the official registers, that refer to many nodes of the
complex of the microprocessor. Depending on the operand that follows after the 
command, it can be with one or two operands:

    1)The loading of the register of the inputting of the operand of the block 
of the ALU:

                             LOAD RA;
                             LOAD RB;

   the given command does not require as second operand to indicate the 
source of the loading or direct operand, because as hardware registers 
are connected to data bus and after presenting the signal record the 
value will be loaded in them, which is at present found on bus.

    2)loading of registers of the marks of the controller of shifts:

                             LOAD  RM;
                             LOAD  RN;
here as the second operand it is possible to indicate necessary values:

    1)Z - loading in all four marks the register of the zeroes;

    2)NZ- loading in all four marks the register of the numeral;

    3)FLAGS - loading in registers signs of execution of last 
             operation in block ALU; with using the operator of the modification 
             @ flags will be loaded in modified type (refer to table of the 
             loading registers of marks);

besides it is possible to load one register by another. The Examples:

                    LOAD RM,Z;
                    LOAD  RN,RM;
                    XOR  R1,R5;
                    LOAD RM,FLAGS;

   The rest of the types of the loading of registers of marks are available 
when the command FIELD is in a use.

    3)The loading of the registers of the mask and conditions of the block of 
      the processing of the interruptions.
   The Command can be with one or two operands. The Difference is that in 
one operanded command registers are loaded by current information from 
data bus  while under direct inputting of the operand of the loading, it 
is brought in the data field of microinstruction and is read on data bus 
from there. For instance:

                    LOAD SR,7;      \register of the condition is with 3 digits,
                                    \remember that attempt to load there number
                                    \greater then 7 will cause a mistake\
                    INC R1;
                    LOAD MR;        \load in register of the mask 
                                    \the incremented value of the register 
                                    \R1(more exactly the younger 8 digits)
