$text = InputBox( "Folder", "Type the folder name" )
DirCreate( @DesktopDir & "" & $text )
I suggest browsing the Example section of the forum. Find a script that interests you. (preferably one commented a lot)
Run it, then read the entire script and figure out which part does what. That's a super-quick way to get a head start. That's what I did.
After that, browse the help file. It's insanely detailed.
