Sure, I can help with that. Here's a step-by-step guide on how Alex can create this utility:

1. First, Alex needs to create a function that takes a string of digits as input. This is because the position of each digit matters and should not be changed.

2. Next, he needs to initialize two variables, `odd_sum` and `even_sum`, both set to 0. These will hold the sum of the digits at odd and even positions respectively.

3. Then, Alex needs to create a loop that goes through each digit in the input string. He can do this by using a for loop that iterates over the length of the string.

4. Inside the loop, he needs to check if the current position is odd or even. He can do this by using the modulo operator (`%`). If the position (plus one, since positions start at 0 in programming) modulo 2 equals 0, then the position is even. Otherwise, it's odd.

5. If the position is even, Alex should add the digit at that position (converted to an integer) to `even_sum`. If it's odd, he should add it to `odd_sum`.

6. After the loop, Alex should calculate the absolute difference between `odd_sum` and `even_sum`. He can do this by using the `abs()` function.

7. Finally, the function should return this absolute difference. This is the result that the program will output.

Here's how the code might look in Python:

```python
def calculate_difference(input_string):
odd_sum = 0
even_sum = 0

for i in range(len(input_string)):
if (i + 1) % 2 == 0:
even_sum += int(input_string[i])
else:
odd_sum += int(input_string[i])

return abs(odd_sum - even_sum)
```

This function will work for any string of digits entered by the user.
