I thought it had already been explained to you that you cannot use MEM[] 
etc. on current operating systems, therefore that is not your "sample 
code": it's stuff that you're asking other people to translate for you.

If you want help on this then post a minimal program that compiles but 
exhibits the problem, i.e. ten lines or so that initialises the video 
stuff, tries to write to it (exhibiting the error) and tidies up.

What's going on here? All of a sudden two people start asking very 
similar questions about MEM[], MEMW[] and so on. If this is classwork 
it's probably safe to assume that your instructor is reading this 
mailing list with interest, perhaps he'd like to fill in what operating 
system etc. your code's supposed to run on since you've not told us >:-)
