WHY SOME COMMANDS DONT WORK IN CMD
LIKE "@" my program always have an error whenever i have this command!

"@" is not a command in any version of MS-DOS or MS-Windows. In the cmd prompt type Help <Enter> and you will get a list of all valid commands.

What command is equal to @ in cmd!cause @ work in 80-86 emulator?

I don't know what @ does.
