Different versions/compilers

newsroom

Hi there,

As I mentioned in a different thread I am just starting off with programming. I choose Pascal mainly because it's the first language you are being thought at uni (at least where I live) and secondly in order to overcome my deep, deep aversion to this programming language (long story). The thing I want to ask is - why there are so many versions (apart of obvious, that is - different platforms) and why so many differences. It's really confusing and makes it that much harder to learn when you try something out just to discover that on your version of compiler it just won't work. That is really frustrating. How can I get my head around the problem? Where do I begin?
