how do i assembly program to find the smallest among two numbers.

assuming that first number is located a memory address : 0x2001 second number is located a memory address : 0x2002

store the smaller number in Accumulator

Here is what i attempted :

LDA 0x2001
MOV B, A
LDA 0x2002
CMP B
JNC smaller
exit
smaller :
MOV A, B
exit : HLT

is my solution correct?

Answer 1

XRA             ; clear the accumulator
MVI B, 30H      ; load a number to B Register
MVI C, 40H      ; load a number to C Register
MOV A, B        ; Move the content of B to A
CMP C           ; Compare value of C against A
JNC SMALL       ; Jump if smaller
**JMP END**         ; Halt program if not small
SMALL: MOV A, C ; save smaller num in accumulator
**END: HLT**
