I am thinking of changing my major to something in the IT field, but I am curious how hard it is to learn to develop web pages or software, these seem to be high in demand. Is it similar to writing a string of codes? I used to work for an airline and had to use the Sabre system which in order to access any information you needed to string together commands, I easily caught on to this, so I am thinking I might learn HTML pretty easy. Any thoughts?
