Extended data:
The console program is set to be compatible with DOS programs. The execution of this program is just like executing in a DOS window, without its own interface.
Intel's CPU has three working modes, real mode, protected mode and virtual mode. The real mode is 16 bits, and pure DOS can run in this mode. The protection mode is 32-bit, and WINDOWS works in this mode. In order to make WINDOWS working in 32-bit protection mode compatible with DOS programs in 16-bit real mode, a virtual mode is set up, which is the console program.
