Consider the 8-instruction programming language given in the text. Show how to implement the following instructions in this language iii. 2 = Vy, where r, y and 2 are variables that can take the values 0 or 1. You may use the instruction go to l. etc. 1. 2. c; (assign x a value specified in the program). M[c; (assign the value stored in Mc). 3. 2+ M[y]; (assign the value stored in M[y]). 4. MC - ; (store in Md the value of variable x). 5. My] + I; (store in M[y] the value of variable r). 6. 2+y+z; (store in the value y + x). 7. 0 -y; (store in the value -y). 132 CHAPTER 4. TURING MACHINES 8. if x > 0 then go to l; (see below).
