Here is the description of a new assembly language: * 8 registers (R1, R2, R3, R4, R5, R6, R7, R8) that can hold integers. * 1 flag that can hold a boolean value (True or False). * 100 memory addresses (0-99) that can hold integers. * 1 instruction pointer that points to the current instruction being executed. Each instruction is of the form OP ARG1 ARG2 ... where ARGn can be either a register (e.g., R1) or a constant (e.g., 10). Labels are written with a lowercase word followed by colon. The assembly language supports the following instructions: * SET Rx C: Assigns the value C to register Rx. * ADD Rx Ry Rz: Adds the values of Ry and Rz and stores the result in Rx. * (similarly for SUB, MUL, DIV, MOD) * EQ Rx Ry: Sets the flag to True if Rx and Ry are equal, False otherwise. * (similarly for NEQ, LT (Rx < Ry), LTE, GT, GTE) * INC/DEC Rx: Increments/Decrements the value of Rx by one. * JMP L: Jumps to label L unconditionally. * JT/JF (jump if true / jump if false) L: Jumps to label L if the is set or not set. * LOAD Rx M: Loads the value at memory address M into register Rx. * STORE Rx M: Stores the value of register Rx into memory address M. * HCF: Stops the program (with pizzazz) Given this assembly language, write a program that puts the first 20 prime numbers in memory cells 0..19

**Explanation:** 1. **Initialization:** * `R1` (prime count) is set to 0. * `R2` (number to test) starts at 2, the first prime. * `R3` (memory address) starts at 0. * `R7` is set to 0 for easy comparison with the remainder. * `R8` is set to 20, our target prime count. 2. **`main_loop`:** * Checks if `R1` (prime count) has reached `R8` (20). If yes (`GTE` is true), jumps to `end_program`. * Resets `R4` (divisor) to 2 for the primality test of the `current_number` in `R2`. 3. **`prime_test_loop`:** * This loop checks if `R2` is divisible by any number from 2 up to `R2 - 1`. * It first checks if the `divisor` (`R4`) has reached the `current_number` (`R2`). If `R4 >= R2`, it means no smaller divisors were found, so the number is prime, and it jumps to `is_prime`. * It calculates the remainder (`MOD R5 R2 R4`). * It checks if the remainder (`R5`) is 0 (`EQ R5 R7`). If it is, the number is divisible by `R4` and therefore *not* prime, so it jumps to `not_prime`. * If the number is not divisible by the current `R4`, it increments `R4` (`INC R4`) and jumps back to the beginning of `prime_test_loop` to try the next divisor. 4. **`is_prime`:** * This code block is reached only if the `prime_test_loop` completed without finding any divisors (or if the number being tested was 2). * `STORE R2 R3`: Stores the prime number (`R2`) into the memory address pointed to by `R3`. * `INC R1`: Increments the count of primes found. * `INC R3`: Increments the memory address for the next prime. * The code then naturally falls through to the `not_prime` label (which in this case just serves as the common point to increment the number being tested). 5. **`not_prime`:** * This label is reached either if a divisor was found (meaning `R2` is not prime) or after a prime number was successfully stored (falling through from `is_prime`). * `INC R2`: Increments the `current_number` to test the next integer. * `JMP main_loop`: Jumps back to the start of the main loop to check if 20 primes have been found and then potentially start the primality test for the new `current_number`. 6. **`end_program`:** * `HCF`: Halts the program execution.
