    Call function by location?

    well in c++ inline asm I wanna call a function based on location like.

    __asm{
    Call 0040001
    }

    instead of doing

    const int loc = 0x0040001;
    __asm{
    call loc
    }

    Code:
    mov eax, 18h
    will set eax to 0x18 so im assuming if you do.....

    Code:
    Call 18h
    it should work Sorry i ain't at home so i cannot verify it but anything is worth a try!

    The address can not be an immediate value.

    mov eax, 40001h
    call eax
