MS Window, from win3.11 to win11 can draw window with or without any border in full screen from EGA to XGA or Full HD, I don't understand why it is not possible in MMBasic.
I have somes progs who use full screen without border, like Maps, for 1 to 4 screen. It work perfect with vb6, but now with win10 and win11, it is more difficulte to execute. For that I can be interesting by MMB, but if it is not possible to work in full screen without border, I must search other langage Lazarus or Purebasic
