AIM: A block of data is stored in memory location from D000H to D004H. Write a program
to transfer the data from one location to another location starting from D010H. Enter the
program on microprocessor kit. Execute the program. Write the contents of both data blocks
before and after execution as well as the contents of the registers used in the program after
execution and the bit contents of five flags individually. Verify the results.

AIM: A block of data is stored in memory location from D000H to D004H. Write a program
to transfer the data from one location to another location in reverse order starting from
D014H. Enter the program on microprocessor kit. Execute the program. Write the contents of
both data blocks before and after execution as well as the contents of the registers used in the
program after execution and the bit contents of five flags individually. Verify the results.

AIM: A block of data is stored in memory location from D000H to D009H. Another block of data
having the same length is stored in memory location starting from D010H. Write a program to
Exchange the contents of these two blocks. Enter the program on microprocessor kit. Execute the
program. Write the contents of both data blocks before and after execution as well as the contents of
the registers used in the program after execution and the bit contents of five flags individually. Verify
the results.
