Go to scriptspot.com and download some scripts, take them apart (after reading some in the manual 🙂 ) .. Also enable the listener if it's off. Check the code it spits out, it doesn't show all commands. but will give valueble information...
First: Create a new maxscript : Maxscript > new script, type in "box name:helloworld" it will create a box on pos 0,0,0
Congratulations your first script! Now put your cursor on box and hit F1, start reading 🙂
Goodluck,
