well, i learnt scar from here

in 2-3 days. BUT i learnt things that are useful for making a seafight script. pascal is a very big language and cant be learnt very easy if you plan to learn everything.
after 1 or 2 days of experimenting and making simple procedures i became pretty good and efficient with it.
then after a week created a pretty good war-tool with some pretty cool functions.
oh and something important, after completing your "studies" in scar, take a look at xriddi's scars. they are very tidy scripts and can make you think of plan of how to make your own script
