Can someone help me with this MIPS problem on MARS, please look at my code.

QUESTION:

Generate a txt file with the following info in each line.

- First Name,

- Last Name,

- Age,

- Gender,

- Phone

Write a MIPS codes that performs the following tasks:

Request a text file name from the user.

Trim the file name

Open the file with the entered file name by the user.

Read the file until the end of the text.

Show the text in the file at the console.

Exit the program by showing an exit message.

MY CODE:

.data

prompt1: .asciiz "Enter first name: "

firstname: .space 20

prompt2: .asciiz "Enter last name: "

lastname: .space 20

prompt3: .asciiz "Enter Age: "

age: .space 20

prompt4: .asciiz "Enter Gender: "

gender: .space 20

prompt5: .asciiz "Enter Phone Number: "

PhoneNumber: .space 20

prompt6: .asciiz "(-1) To exit:"

prompt7: .asciiz "(0) To update information:"

prompt8: .asciiz "(1) To write infromation into a file with a comma after each field:"

ExitEnter: .space 20

fin: .ascii ""

msg1: .asciiz "Please input name for text file: "

exiting: .asciiz "Thank you for the information. Saving and closing the file and exiting the program."

inputbuffer: .space 51

buffer: .asciiz ""

comma: .asciiz ","

newline: .asciiz " "

.text
