There's still a command prompt in 32-bit WIndows 10.
I have upgraded (so to speak) a computer from Windows 8.1, 32-bit, and I clicked on editor.exe in C:\XY. Our little program simply ran--but in a tiny window, 8-point type, which had to be changed in Properties or Defaults (I don't know which one worked).
However, it runs better and in a larger window under VDosXY, the gift that keeps on giving.
If anyone else is going to try Windows 10, be advised that it is a privacy disaster. Obviously none of us would use the Express install. But even after a custom installation (and refusing to Personalize, which lets MS record every keystroke), you need to go into Settings/General and Settings/Privacy and turn off a dozen things that Windows 10 automatically opens . Or just stay with 8.1.
