Write an Assembly Language Program to arrange given numbers in ascending order

 Algorithm

1. Initialize HL pair as memory pointer

2. Get the count at 4200 into C - register

3. Copy it in D - register (for bubble sort (N-1) times required)

4. Get the first value in A - register

5. Compare it with the value at next location

6. If they are out of order, exchange the contents of A - register and Memory

7. Decrement D - register content by 1

8. Repeat steps 5 and 7 till the value in D- register become zero

9. Decrement C - register content by 1

10. Repeat steps 3 to 9 till the value in C - register becomes zero

LXI H,5000    ;Set pointer for array    

          MOV C,M       ;Load the Count

          DCR C         ;Decrement Count

  REPEAT: MOV D,C

          LXI H,5001

    LOOP: MOV A,M       ;copy content of memory location to Accumulator

          INX H

          CMP M

          JC SKIP       ;jump to skip if carry generated

          MOV B,M       ;copy content of memory location to B - Register

          MOV M,A       ;copy content of Accumulator to memory location

          DCX H         ;Decrement content of HL pair of registers

          MOV M,B       ;copy content of B - Register to memory location

          INX H         ;Increment content of HL pair of registers

    SKIP: DCR D         ;Decrement content of Register - D

          JNZ LOOP      ;jump to loop if not equal to zero

          DCR C         ;Decrement count

          JNZ REPEAT    ;jump to repeat if not equal to zero

          HLT           ;Terminate Program
