I am porting a DOS application to Windows environment. Can I use in-line
assembly to make an interrupt call ? It's not the regular int 21h or int 5Ch.
e.g.
_asm {
push ds
push ax
mov ax, 0DE11h ; some function code
int 78h ; call ISR
pop ax
pop ds
}
Can I use 32-bit registers instead of 16-bit ? If I choose to write a separate
assembly file, can I write truely 32-bit programme ?
Thanks !
