(i.e., the BEQ branch instruction on line 14 will examine the right status of program execution to determine the branch condition.) 3) Revise the program so the “Ptr RMB 2” on line 6 will not be used. Instead, Register X points to the element in Table 1, and Register Y points to the element in Table 2. Hey All, I'm stumped on this question.For the third one, my specific question has to do with the Tables.Does X point to Space and Y point to Length? I have no clue what table is being referred to. For the second one, does that mean that i completely remove the TST line along with the rest of the loop at line 23?

What does it mean to examine the 'right status' of the program? Any help would be very nice.Thanks. Regarding (2): Certain instructions (including all LOAD and STORE instructions) modify the Condition Code Register (CCR) according to the result of the operation. So, if you place your conditional branch after such instructions, an explicit TST instruction becomes redundant. Regarding (3): This is a copy routine. You're copying from a source location (beginning at $7F) to a destination location (beginning at $9D). You can think of these as arrays or tables.
