in mips if
i have this code below how tould i take that string that was inputed and toggle the case.
For example "My nAmE is JhON" would output "mY NaMe IS jHon"
in other words uppercase toggles to lower case and lowercase toggles to upper case

Transcribed Image Text:This is a simple assembly program written for the MIPS architecture. Here's the program code transcribed:
```assembly
.data
userInput: .space 80
.text
.globl main
main:
# gettin text from the user
li $v0, 8
la $a0, userInput
li $a1, 80
syscall
# displays the name
li $v0, 4
la $a0, userInput
syscall
# toggles the case
btl $v0
# end of ile
li $v0, 10
syscall
```
### Explanation
1. **Data Segment (`.data`)**
- `userInput: .space 80`: Reserves 80 bytes in memory for user input storage.
2. **Text Segment (`.text`)**
- `.globl main`: Declares the `main` function as a global label, making it accessible to the program loader.
3. **Main Function (`main`)**
- **Get User Input**
- `li $v0, 8`: Load immediate value `8` into register `$v0`. This prepares the syscall for reading a string.
- `la $a0, userInput`: Load the address of `userInput` into register `$a0`.
- `li $a1, 80`: Load immediate value `80` into register `$a1`. This indicates the maximum number of bytes to read.
- `syscall`: System call to read a string from the user.
- **Display User Input**
- `li $v0, 4`: Load immediate value `4` into register `$v0`. This prepares the syscall for printing a string.
- `la $a0, userInput`: Load the address of `userInput` into register `$a0`.
- `syscall`: System call to print the string.
- **Toggle Case (Incorrect Instruction)**
- `btl $v0`: This appears to be an error (`btl` is not a standard MIPS instruction). The intended function might be to toggle the case of characters.
- **End Program**
- `li $v0, 10`: Load immediate value `10` into register `$v0`. This prepares the syscall to exit
