how can i set a program to be autostart in DOS?

Question

I mean when i power on the computer after DOS starts the program starts automaticly

Answer 1

Type the path to the program & the executable file that starts it into your "Autoexec.bat" file.

Type "edit c:\autoexec.bat"
This starts the DOS editor (blue background) & what you see are all the line instructions in the Autoexec file.

Go to the bottom of the list & add (for example) :
"c:\games\mario\mario.exe"

This command will start the Mario game as soon as the PC boots into DOS.

email me if you run into difficulty,
