Question

Prepare a MARIE subroutine called printStringName that can print any name containing two ASCII ‘0’ terminated strings (using the “Output” instruction). Start by using a label “PrintName” that holds the start address of a name string (like, myNameAdd in the example above). The code should then load a character from that address, output it if it is not ‘0’, then increment the address by one, and keep doing that until the character loaded from the address is a ‘0’ (which signals the end of the string). Then, print an ASCII “Space” character, and proceed to print the second part of the name string, i.e. Last Name until the character loaded from the address is a ‘0’ (which signals the end of the string). Then, when you load the second ASCII ‘0’ which marks the “end of a name”, print an ASCII “New Line” character and proceed to print the next name. For this task, you may use two or three names (your First Name and Last Name, your teacher’s name, your tutor’s name etc. minimum two names) to print, each name hard coded and assigned a label to identify. To receive full marks, your code needs to be in the form of a subroutine that can be called using the JnS instruction. You need to write a MARIE main program to call this subroutine.
