Sure, here is the program in Python 2.7:

def convert_string_to_numbers(input_string):
result = []
for char in input_string.upper():
if ord(char) >= 65 and ord(char) <= 90:
result.append(ord(char) - 64)
return result
input_string = raw_input("Enter a string: ")
numbers_list = convert_string_to_numbers(input_string)
print("Numbers from the input string:")
for num in numbers_list:
print(num)

To run the program, simply copy and paste the code into a Python 2.7 interpreter or IDE. Then enter a string and the program will output the numbers corresponding to the letters in the input string.
