8086 PROGRAM TO MULTIPLY TWO 8-BIT BCD NUMBER

In assembly language 8086 we use mnemonics in order to perform arithmetic operations like  in MUL/IMUL subtraction.
So, Let's dive deep into what  MUL and IMUL is ...

MUL:- It multiplies unsigned byte/word from source with unsigned byte/word in AL/AX register.
Operation:-
When source is BYTE  then, AX← AL* unsigned 8-bit source
When source is BYTE  then, DX: AX← AX* unsigned 16-bit source

IMUL:- It multiplies signed byte/word from source with signed byte/word in AL/AX register.
Operation:-
When source is BYTE  then, AX←  AL* signed 8-bit source
When source is BYTE  then, DX: AX←  AX* signed 16-bit source

Which flags get affected?
Ans- OF , CF, PF , AF, SF , ZF
