I can't figure out the table for VertMenu()
I think you should add a bit more instructions to your post.
Otherwise, this is pretty cool, and looks clean... I'm probably gonna use it for a Stats Program I'm making. (Shows the status of all your industry's stuff)

table={"all","my","stuff"}
table2={"in","here","done"}
result = VertMenu(table)
result2 = Vertmenu(table2)

This makes it so if you select anything from table it shows everything from table2
how do I make it so if I choose "all" It shows table2 and if I choose "my" it shows everything from table3
or
if I choose "all" it shows table2[1] and if I choose "my" it shows table2[2]

You make use of an if statement

result = {}
if result[1] == this then
	result[2] = something
  
elseif result[1] == that then
	result[2] = something_else
  
elseif result[1] == other then
	result[2] = another_thing
  
end
if result[2] == even then
	result[3] = something_again
  
elseif result[2] == more then
	result[3] = something_new
  
elseif result[2] == things then
	result[3] = another_thing_entirely
  
end
--and so on and so forth....

Instead of making the result table equal to those made up variables, you can call the menu function to generate sub menus.

EDIT: In fact I get this question so often I have put some sample code under the VertMenu section (in a spoiler) to show how this might be done.

hey im trying to get the load bar to work on startup alongside my user login screen but i keep getting the following error :
bios:338: [string "startup"} :19: "=" expected

Here is my code

print("Prototype OS V0.01")
write("Login: ")
lanswer = read()
if lanswer == "Pivotdude" then
write("Password: ")
else
os.reboot()
end
panswer = read()
if panswer == "1337" then
print("Welcome "..lanswer..".")
else
os.reboot()
end
term.clear()
function HorzLoadBar(sx, fx, sym)
start x, finish x, "<symbol>"
end
function HorzLoadBar(sx, fx, sym)
x,y = term.getCursorPos()
if y >= 18 then
		term.clear()
		term.setCursorPos(sx,1)
		x,y = sx,1
end
term.setCursorPos(sx,y)
write("[")
term.setCursorPos(sx,y)
term.setCursorPos(fx-1,y)
write("]")
mdp = math.floor((sx + fx)/2) - 3
for i = (sx+1),(fx-2) do
		term.setCursorPos(i,y)
		write(sym)
		sleep(0.1) --CHANGE THIS TO EDIT TIME
		term.setCursorPos(mdp,y+1)
		write(string.format("%d",i/(fx-2) * 100))
		write("%")
end
term.setCursorPos(1,y+2)
end

EDIT: i am using the standard non advanced computer , should i be using the golden advanced one?
EDIT II: if i use brackets around the command in the function permameter its the same error except from the fact that ) is expected instead of =

Try something like this, I dont have the time to test if it works now, but I noted that the function 'HorLoadBar' was in there twice, the 1 one causing the error.

You don't say TUI...

You say CLI (Console Line Interface).
But even if you are using ASCII, it's still GUI.

Okay so i fixed it but i wanted to point out that i have not a single clue on what im doing since im new to CC however how would i center the login and the loadbar? i tried a general center function but it contradicts the other lines of code with multiple quoted brackets and stuff. also i am using notepad ++ to code (screw rewriting code - i did however do the loadbar 100% in CC prior to realising np++ read CC programs which can be seen by my mistake in the code)

Thanks, I have changed the description.

You googled it up or you already knew?

Sadly enough I already knew. One of the side affects of being an electrical engineer.

As far as I can tell the only thing that is missing here is that your menu program does not actually do anything. The function is there but you don't call it, or pass it anything.
