Add two 16 bit number using Assembly Level Language

Here, am gonna illustrate you how to add two 16 bit numbers from Assembly level Language.
Here we go,


The full code is as,
LDA 2050
MOV B,A
LDA 2051
ADD B
JNC label
INR C
label: STA 2053
MOV A,C
STA 2054
HLT


Here,
LDA 2050
        It means, load accumulator with data of 2050 memory address.
Now, it becomes A = data of 2050 
MOV B,A
        It means, Move data of Register A to register B.
LDA 2051
        Same as first one.
ADD B
       It means, add  the content of  register B to A and put output on A.
JNC label
       It means, if carry occurs no jumping to label, else jump to label.
INR C
         Increase C register by 1.
label: STA 2053
         Store the content of accumulator in 2053 address memory

Similarly, the steps are followed..

Finally, we get Our result at   2053 with carry at 2054. HLT terminate our program.
