+local function newmenu(tList,x,y,height)
-call newmenu with a table as the first parameter, the table is a list of all options in the menu, if you like you can specify a table as one/more of the options, it will then show the first value in that table as the choice and will call the second value as a function if you select that option, it will call the function with the option as a parameter and the newmenu function will return whatever your choice returns. if the choice is not a table then it will simply return the string that is the choice. example:
+	local function maxlen(t)
-
+		local len=0
-newmenu({1,2,3,4},2,2)
+		for i=1,#t do
-
+			local curlen=string.len(type(t[i])=='table' and t[i][1] or t[i])
-would generate a menu where you can choose 1; 2; 3 or 4 and if you choose 2 it will return 2. the menu will start at CDS 2,2
+			if curlen>len then len=curlen end
-
+
-newmenu({1,{2,function(param) return print('you selected '..param) end},3,4},2,2)
+		return len
-
+
-would generate an identical looking menu but this time if you select 2 it will call the function there with param=2 and the newmenu function will return whatever the function returns
