PROGRAMS Steps to write a program:-     Type the starting memory address using keyboard, in this 8085kit address belongs to C000 to FFFF. We can use any memory address between them. Ex: A C000 here A stands for assemble the program.       After that counting type the to the end.      Whenever label is given type their corresponding memory address where we want to jump our program.       When complete program is typed then enter key is pressed two times to execute the program. Steps to execute a program:-       Type G< starting address>, then press enter key, after that space key.       Type R, then press enter key. Which given the content of registers.       When memory address is given in program following step are performed. A.    Type E<memory address>, then press enter key. Here memory address is the address where data is entered which is already mention in program. B.     After that step 1 is performed. C.     Type D<memory address>, then p
