can u help n explain 2 me to write 8085 instruction for this program?

I guess I can provide you some hints of code. Its not tested and you need to be doing it yourself.

Can you explain what you meant by 3 consecutive memory locations.

Re: 8085 ALP instruction problem
 

3 consecutive memory location for example;

data will be point to memory location n stored at 5200,5201,5202 memory location

Re: 8085 ALP instruction problem
 

That can be done with
STA Y
STA Y + 1
STA Y + 2

Re: 8085 ALP instruction problem
 

I don't know exactly
but to unpack a number

LDA 8200
MOV B,A
ANI 0F
MOV C,A
MOV A,B
ANI F0
RRC
RRC
RRC
RRC
MOV B,C


FROM THE ABOVE PGM
A CONTAINS FIRST UNPACKED NO.

AND

B CONTAINS SECOND UNPACKED NO.
