Please help me fix the following code, it is supposed to print (centered) 'CS 220' on the Nand2Tetris screen which uses the CPU Emulator and loaded ROM and RAM registers. The code is not working its only printing a small sliver of pixels onto the top left of the screen.// Built-in constant in Assembly // @SCREEN // A=16384// D=A // Let's say we start at address 16640 (this is where our text will be placed)@16640D=A // D = 16640 (starting address for text)@addressM=D // store starting address in 'address' variable // Initialize count to 0 (start counting for 6 characters)@countM=0 // initialize the count to 0 (LOOP)@6D=A // D = 6 (total number of characters to print)@countD=M-D // D = count - 6@ENDLOOPD;JGE // if count >= 6, jump to ENDLOOP // Place character 'C' (ASCII 67) at current address@67D=A // D = 67 (ASCII value for 'C')@addressA=M // A = current addressM=D // Store 'C' at the current address // Move to the next memory location (increment by 1)@addressM=M+1 // Increment address by 1 // Place character 'S' (ASCII 83)@83D=A // D = 83 (ASCII value for 'S')@addressA=M // A = current addressM=D // Store 'S' at the current address // Move to the next memory location@addressM=M+1 // Increment address by 1 // Place space character ' ' (ASCII 32)@32D=A // D = 32 (ASCII value for space)@addressA=M // A = current addressM=D // Store space at the current address // Move to the next memory location@addressM=M+1 // Increment address by 1 // Place character '2' (ASCII 50)@50D=A // D = 50 (ASCII value for '2')@addressA=M // A = current addressM=D // Store '2' at the current address // Move to the next memory location@addressM=M+1 // Increment address by 1 // Place another '2' (ASCII 50)@50D=A // D = 50 (ASCII value for '2')@addressA=M // A = current addressM=D // Store '2' at the current address // Move to the next memory location@addressM=M+1 // Increment address by 1 // Place character '0' (ASCII 48)@48D=A // D = 48 (ASCII value for '0')@addressA=M // A = current addressM=D // Store '0' at the current address // End of program, prevent further operations@END0;JMP (END)

Question

// @SCREEN // A=16384
// D=A

// Let's say we start at address 16640 (this is where our text will be placed)
@16640
D=A // D = 16640 (starting address for text)
@address
M=D // store starting address in 'address' variable

// Initialize count to 0 (start counting for 6 characters)
@count
M=0 // initialize the count to 0

(LOOP)
@6
D=A // D = 6 (total number of characters to print)
@count
D=M-D // D = count - 6
@ENDLOOP
D;JGE // if count >= 6, jump to ENDLOOP

// Place character 'C' (ASCII 67) at current address
@67
D=A // D = 67 (ASCII value for 'C')
@address
A=M // A = current address
M=D // Store 'C' at the current address

// Move to the next memory location (increment by 1)
@address
M=M+1 // Increment address by 1

// Place character 'S' (ASCII 83)
@83
D=A // D = 83 (ASCII value for 'S')
@address
A=M // A = current address
M=D // Store 'S' at the current address

// Move to the next memory location
@address
M=M+1 // Increment address by 1

// Place space character ' ' (ASCII 32)
@32
D=A // D = 32 (ASCII value for space)
@address
A=M // A = current address
M=D // Store space at the current address

// Move to the next memory location
@address
M=M+1 // Increment address by 1

// Place character '2' (ASCII 50)
@50
D=A // D = 50 (ASCII value for '2')
@address
A=M // A = current address
M=D // Store '2' at the current address

// Move to the next memory location
@address
M=M+1 // Increment address by 1

// Place another '2' (ASCII 50)
@50
D=A // D = 50 (ASCII value for '2')
@address
A=M // A = current address
M=D // Store '2' at the current address

// Move to the next memory location
@address

// Place character '0' (ASCII 48)
@48
D=A // D = 48 (ASCII value for '0')
@address
A=M // A = current address
M=D // Store '0' at the current address

// End of program, prevent further operations
