ASCII-Binary conversion in Assembly Language
Write a Assembly program for ASCII-Binary conversion with proper output . First of all do ASCII-Gray conversion by Dividing the ASCII number by 2 until the quotient is 0 .
Algorithm for ASCII-Binary conversion
Step I : Get the number whose binary code equivalent is to be found.
Step II : Initialize count in CL = 08 H
Step III : Divide the number by 2 i.e. shift the number by 1 it to the left.
Step III : Display the bit shifted in carry.
Step IV : Decrement count
Step V : Check if count =0 ?
Step VI : If yes go to step VII else go to step III.
Step VII : Stop.
