greetings! you've come to the right place - full of friendly helpful individuals, not to mention a host of very good tutorials dealing with just about everything that you could think of concerning flashpoint.
as for the language, flashpoint uses its own proprietary language for scripting, but from what i can tell the basics of most programming languages are still there - variables, loops, if/then decisions. it's just how you write them which is different. only by looking at other people's scripts and through trial and error will you learn.
i would suggest going to the editor's depot (link at the top of the page) and having a look at the 'getting started' tutorials. they're easy to read, cover all the basics and will have you mission-making in no time.
welcome once again, and happy hunting!
