Ehm... well... let's say that I had some fun in the 90s :D
The second impact, 2 years ago, was pretty brutal since I was used to code using Object oriented programming but after that hit I started to regain my memories and make use of arrays and memory banks, I struggled a bit in the first months :)
There are plenty of manuals around and many example code, also the examples included with AMOS Pro are a good starting point!
