8086 program to convert 8 bit ASCII to BCD number

Problem – Write a program to convert ASCII to BCD 8-bit number where the starting address is 2000 and the number is stored at 2050 memory address and store result in 3050 memory address.

Example-
Input  : location: 2050
         Data   : 37
Output : location: 3050    
         Data   : 07        

Algorithm –

1. Move value at [2050] into AL
2. Perform AND operation on AL with 0F
3. Move the content of accumulator AL into 3050
4. Stop

Program –

Memory	Mnemonics	Operands	Comment
2000	MOV	AL, [2050]	[AL] <- [2050]
2004	AND	AL, 0F	[AL] <- ([ AL] AND 0F )
2006	MOV	[3050], AL	[3050] <- [AL]
200A	HLT		Stop

Explanation – Registers AL is used for general purpose

1. MOV is used to transfer the data
2. AND is used for multiplication (logically)
3. HLT is used to halt the program
