No, adding up the number of blocks in each file gives you

	acctrpt		3
	age.csh		1
	arcjobs.sh	2
	deltime	       29
	mailbarry	1
	mailjim		1
	newsindex	1
	tmp		2

	total	       40 blocks exactly.

Because, Oh Great Dweeb, ls reports in blocks, and since the entire block
must be used, it tells you just how big the file is IN BLOCKS.  Try it on
an old system - BUT THEN - the entire world is running on a Vax!

For the next part, how you divided 35,725 bytes by 1024 and came up with
35.7 KB is beyond me.  I did the division and came up with 34.887 KB.

Is this guy a yuppy undergrad?  What is it with these undergrads anyway?

Oh yes, time for a yuppy joke.

What is the difference between a yuppy and a pigeon?

The pigeon can still make a deposit on a BMW.
