The test next week!
Lab on Monday:  Practice problems, kinda like tests have

Advising note:
	CS253 next Fall, hybrid courses in general
	3D Structure Generation with Python in Blender

Files on Unix:
	How platform dependent will this be?
		Windows does have "file handles"
	Cross-platform functions:
		fopen, c++ input streams, Python files, etc.
		You could make a file class with a different version for each OS
		C++ is cross-platform because it does something different on each OS
	Here in assembly, we're NOT cross-platform!
		Today's programs probably won't even run on BSD without modification!
	0, 1, 2:  Standard in, out, error
		cin, cout, and cerr in C++
		C++ on Windows replicates that functionality with Windows API calls
	But let's open a file by name!
		And put text in it!

Binary vs. Text files:
	The difference is all in your head
	Basically, a text file avoids byte values that aren't ASCII characters
	Let's edit a compiled program to say something different

*nix, and tables:
	An open file table is held for each process

What can you do with a file?
	open (files that are actually files only)
	read
	write
	lseek (unless it's a network socket, standard in, etc)
	mmap (Again, unless it represents sequential data)
	Monitor it for additions (with select, or a blocking read)
		tail -f demo
	Look at Wikipeda for a big list

Read from a file:
	Can we read an array of 10 numbers?
	It'll have to go somewhere (stack allocation)
	We can put some numbers into a file from C
		Couldn't we do this in assembly?
		Lazy...
