flash function that checks if input text is the same as text from file

Hello!

I am making a Flash AS2 project for word learning and I would like to know Your opinion and advice on this topic :

I have this word check task, where You have to write(input text) the correct names under these 3 pictures and check if You have written them correctly with the button - "CHECK!"

It would be simple, but there is a mandatory requirement that the inputed text must be compared to a text from file and then checked if they match.

I added a picture for better understanding..

Is this possible in AS2?

Thank You!
