Hello everyone!
This is the code for my A86 Assembler:

jmp _executor

_executor:
    mov ah, 00
    mov al, 18
	
    int 10h
end _executor

It Assembles fine, but when I try to run it, I get this dialog popping up, saying:

This system does not support fullscreen mode. Choose 'Close' to terminate the application.

And the title of the dialog is: "16-bit MS-DOS Subsystem".
And I get this dialog, no matter what graphics mode I use!
Please help me :).

Video mode 12h (=18) is unusable in fullscreen in recent Microsoft OS. Try to adjust compatibility mode to Win 98, or execute your program in an emulator like DOSBox
