Running the OpenOS Editor from a program

[Elektron72 2]

I am making a program where one of the functions is to open the editor. However, I noticed that part of the program's code seems to interfere with the editor. When the editor is opened by my program, it freezes immediately after displaying the file and will not accept any input. What part of the code is responsible for the issue?

Here is a standalone version of the broken code (https://pastebin.com/CppRwXqh) :

local filesystem = require("filesystem")
local shell = require("shell")
local process = require("process")
local cellLocation
local i
local j
local tempchar
 
function createProgramList()
  cellLocation = shell.resolve(process.info().path)
  cellLocation = filesystem.canonical(cellLocation .. "/..")
  print(cellLocation .. "/programs.cfg")
  io.input(cellLocation .. "/programs.cfg")
  programs = {}
  i = 1
  while 1 do
    print("Loading program #" .. tostring(i) .. "...")
    programs[i] = {}
    print("Loading name...")
    while 1 do
      tempchar = io.read(1)
      if tempchar == ";" then
        break
      elseif programs[i][1] ~= nil then
        programs[i][1] = programs[i][1] .. tempchar
      else
        programs[i][1] = tempchar
      end
    end
    print("Loading option name...")
    while 1 do
      tempchar = io.read(1)
      if tempchar == ";" then
        break
      elseif programs[i][2] ~= nil then
        programs[i][2] = programs[i][2] .. tempchar
      else
        programs[i][2] = tempchar
      end
    end
    programs[i][3] = {}
    j = 1
    print("Loading file associations...")
    while 1 do
      tempchar = io.read(1)
      if tempchar == "," then
        j = j + 1
      elseif tempchar == ";" then
        break
      elseif programs[i][3][j] ~= nil then
        programs[i][3][j] = programs[i][3][j] .. tempchar
      else
        programs[i][3][j] = tempchar
      end
    end
    print("Loading run syntax...")
    while 1 do
      tempchar = io.read(1)
      if tempchar == nil or tempchar == "\n" then
        break
      elseif programs[i][4] ~= nil then
        programs[i][4] = programs[i][4] .. tempchar
      else
        programs[i][4] = tempchar
      end
    end
    if tempchar == nil then
      break
    end
    i = i + 1
  end
end
 
createProgramList()
shell.execute("edit /init.lua")

Also, a file named programs.cfg is necessary in the same directory containing the following text:

;;;

Changing from io.input() to io.open() fixed the problem.
