Hi.

I think everyone develops his owny coding style with the time.. a lot of time
So if you know some ground rules, it should be ok. You have a base to start.
The other good way to learn is to read a sources from others. Read sources of freepascal or Delphi, those guys know how to write good code.

And if after some time you will look at your old code and you think "what a mess, I could do it a lot better now" thats the sign that you have moved forward

good luck
