Question about the Scrolling event.

Hello,

I'm trying to make a simple database to save passwords so I can do something with it later.
Everything is working good so far. But If I got more then 10 users, then I cant put it on one page.
So I thought maybe if I use a Scrolling system so if I scroll down I can see the rest of the users
and If I receive the top again the its stops so you cant go further from the top. But I already tried some few
things, but I dont know how to do it.. I got a Table where I stored the {Username, password} and I dont know if you scroll
down how to print the other users in the table. So I need to know how to use the function and if it reached the top again it stop.

Acc_pass = {}

function userScrolls()

while true do
for n, account in pairs(Acc_pass) do
event,arg,x,y = os.pullEvent("mouse_scroll")
term.setCursorPos(x,y)
term.setTextColor(colors.black)
term.scroll(arg)

end
end
end

Tiny bit of math involved here. You need to keep track of how far you've scrolled, and you also need to keep track of how far you can scroll - which depends on the length of the list, versus the length of the screen.

Something along these lines:

local function listScroll(list)
	term.setTextColour(colours.white)
	term.setBackgroundColour(colours.black)
	
	local scrollPos = 1
	
	local xSize, ySize = term.getSize()
	
	while true do
		term.clear()
		for i = 1, math.min(#list, ySize) do
			term.setCursorPos(1, i)
			term.write(list[scrollPos + i - 1])
		end
	
		local myEvent = {os.pullEvent()}
		
		if myEvent[1] == "mouse_scroll" then
			scrollPos = scrollPos + myEvent[2]
			if scrollPos > #list - ySize + 1 then scrollPos = #list - ySize + 1 end
			if scrollPos < 1 then scrollPos = 1 end
			
		elseif myEvent[1] == "char" or myEvent[1] == "mouse_click" then
			return
		
		end
	end
end

listScroll({"this","is","an","example","of","a","list","this","is","an","example","of",
	"a","list","this","is","an","example","of","a","list","this","is","an","example",
	"of","a","list","this","is","an","example","of","a","list","this","is","an","example",
	"of","a","list"})
