Big reactor

I am writing a program to control my big reactor but i am stuck on making the UI. I cant get it to enter the computer to enter the if statement, it just ignores it.

print("Press 1 to edit control rod settings")
a = io.read()
if a==1 then
   print("Enter Control Rod settings")
End

io.read() always returns strings, but 1 is a number: so your condition will never be true.

You could do:

if a=="1" then

Or, instead:

a = tonumber(io.read())
