please help me fix the following code to display the string 'CS 220' in the Nand2Tetris screen which uses the CPU Emulator it is supposed to initialize the screen memory location at the middle of the screen....the CPU Emulator has 32767 ROM addresses and 24576 RAM addresses.// Built-in constant in Assembly // @SCREEN // A=16384 @16384 // SCREEN base addressD=A@SCREEN_ADDRM=D // store SCREEN base address in SCREEN_ADDR // Calculate the starting address for centered text (row = 6, column = 20)@32 // Row offset: each row has 32 addressesD=A@6D=D*A // D = 192 (row offset for row 6)@20 // Column offset: 20th columnD=D+A // D = 212 (starting address for row 6, column 20)@SCREEN_ADDRD=M+D // Calculate starting address@ADDRESSM=D // store starting address in ADDRESS // Initialize count to 0 (start counting for 6 characters)@COUNTM=0 // initialize the count to 0 // Character 'C' (ASCII 67)@67D=A // D = 67@ADDRESSA=M // A = current addressM=D // Store 'C' // Move to the next memory location@ADDRESSM=M+1 // Increment address by 1 // Character 'S' (ASCII 83)@83D=A // D = 83@ADDRESSA=MM=D // Store 'S' // Move to the next memory location@ADDRESSM=M+1 // Increment address by 1 // Space ' ' (ASCII 32)@32D=A // D = 32@ADDRESSA=MM=D // Store space // Move to the next memory location@ADDRESSM=M+1 // Increment address by 1 // Character '2' (ASCII 50)@50D=A // D = 50@ADDRESSA=MM=D // Store '2' // Move to the next memory location@ADDRESSM=M+1 // Increment address by 1 // Character '2' (ASCII 50)@50D=A@ADDRESSA=MM=D // Store '2' // Move to the next memory location@ADDRESSM=M+1 // Increment address by 1 // Character '0' (ASCII 48)@48D=A@ADDRESSA=MM=D // Store '0' // End of program@END0;JMP (END)
