Thanks for watching Karim! I have a few other videos that are just about loops: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-AOws395_dWM.html and ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IF6FFqfjOXE.html hope they help. I don't have a video about global variables, I will add that to my to-do list.
