They can be used together without any issues on platforms providing sufficient access to the console. *it means i cann't use write/Writeln function using video unit* i just want to check at particular screen location value exist or not using Videobuf ( ex. If VideoBuf[Offset ' ' Then Begin ...End]) . i can check but i cannt use any crt function with VideoBuf. Indeed, you should not mix access to the console using Crt.Write(Ln) with access via Video.VideoBuf^. On the other hand, you can use Video.VideoBuf^ together with keyboard related functions from unit Crt (with the caveat that it would work on e.g. Win32 but not e.g. on Linux). Vice versa, you may be able to use functionality provided by unit Video for changing the console resolution (under Win32) together with Crt.Write(Ln) as long as you re-initialize the window coordinates (Crt.Window) after Video.SetVideoMode and before any Crt.Write(Ln).

Or you can do the right thing and not use the contents of the video memory as if it were a variable to be used to check if you have or have not done a particular thing, which is what it looks like your original code does. This would require understanding more of what the program you are porting was intended to do and less of how it did it. Once you have that, so many questions answer themselves.
