The document discusses logic, shift, and rotate instructions in computer programming. It defines logic instructions like AND, OR, XOR, and NOT that manipulate individual bits, treating 0 as false and 1 as true. It also defines shift instructions that shift bits in a destination operand left or right by a specified number of positions. Rotate instructions similarly shift bits but also put the bit shifted out from one end back in on the other end. An example program is given that prompts a user to enter two binary numbers and prints their sum in binary.

4. Logic instruction
 To manipulate individual bits
 Binary Value 0 treated as false
 Binary Value 1 treated as true
 AND
 OR
 XOR

 TEST

5. SHIFT AND ROTATE INSTRUCTION:
Shift:
Shift the bits in destination operand by
one or more positions either to the left or
right.

6. Syntax:
SHL DESTINATION,CL
SAL DESTINATION,CL
SHR DESTINATION,CL
SAR DESTINATION,CL

7. ROTATE:
Bit shifted out from one end of
the destination operand is put
back on the other end.

8. SYNTAX:
ROL DESTINATION,CL
ROR DESTINATION,CL

9. Program:
An AL Program that prompts the
user to enter two binary numbers of
up to 8 digits each, and print their
sum on the next line in binary. If the
user enters an illegal character, he
or she should be prompted to begin
again. Each input ends with a
carriage return.
