lc3

I am writing an LC3 program that increments each letter of a three-letter word stored in memory following the program. 'a' becomes 'd', 'n' becomes 'q', 'z' becomes 'c', etc. I am using this as LC3 Assembly a reference Here is my code so far .orig x3000 ADD R1, R1, #3 LEA R2, STRING HALT STRING .STRINGZ "anz" .END I was able to figure out how to declare a string of characters in LC3 from my reference. However does anyone how to do the actual incrementation or have any references that I could use to figure out how to do it? Using a while loop, I was able to get it to increment each char of the

I am writing an assembly program on the LC3 machine. My assembly program is an LC3 program that multiplies R2 and R3 and stores the result in R1. Here is my source code(with comments) ;Sets pc to this address at start of program .ORIG x3000 ;R1 will store the result lets clear it(ANd with 0) AND R1,R1,x0 ;R2 will be multiplied by R3, let's clear both of them AND R2,R2,x0 AND R3,R3,x0 ;Test case 4 * 3 = 12; ADD R2,R2,4 ADD R3,R3,3 ;Add to increment zone LOOP Add R1,R1,R2; ;Decrement the counter, in this case the 3 or R3 ADD R3,R3,x-1 BrP LOOP HALT .END My test case is multiplying 4 * 3.
