Let's analyze the provided code step by step to answer the questions.

### Code Analysis
1. **Input Statement**: `Input "any string" ;A$`
   - This line prompts the user to input a string, which will be stored in the variable `A$`.

2. **Loop**: `FOR I=1 TO LEN(A$)`
   - This loop iterates from 1 to the length of the string `A$`.

3. **Print Statement**: `PRINT MID$(A$,1,1);`
   - The `MID$` function extracts a substring from `A$`. Here, it extracts the first character of the string (starting at position 1 and taking 1 character).
   - The `PRINT` statement outputs this character.

4. **Next Statement**: `Next I`
   - This indicates the end of the loop, and it will continue to the next iteration until `I` exceeds the length of `A$`.

5. **End Statement**: `END`
   - This signifies the end of the program.

### i. Output for Input String "NEPAL"
- The input string is "NEPAL", which has a length of 5.
- The loop will iterate 5 times, and in each iteration, it will print the first character of the string "NEPAL".

However, since the `MID$` function is always extracting the first character (position 1), the output will be:
```
N
N
N
N
N
```
So, the output will be the character "N" printed 5 times, each on a new line.

### ii. Two Library Functions in the Program
1. **LEN**: This function returns the length of the string `A$`.
2. **MID$**: This function extracts a substring from the string `A$`, starting at a specified position and for a specified length.

### Summary
- **Output for "NEPAL"**: 
  ```
  N
  N
  N
  N
  N
  ```
- **Two Library Functions**: `LEN`, `MID$`.
- **Output for "NEPAL"**: ``` N N N N N ``` - **Library Functions Used**: `LEN` and `MID$`.
