it's the offset

In general, your file begins at 0x0000h, and then it's shown at 16 bytes each time. So the next address is 0x0010h (that's 16 bytes = 10h bytes).

In your example, you are showing at 200h bytes from the begining, and then 210h bytes from the begining... :)

wouldn't "offset" be the correct term? (offset from start of file, 0 being the start) – horatio Apr 19 '12 at 17:17
Wouldn't it just be the same thing.. – cutrightjm Apr 19 '12 at 17:19
@horatio Perfect, it's "offset" the most common name. I'll edit my answer, when I was typing it I completly forgot the name and used the generic "address" – woliveirajr Apr 19 '12 at 17:20
@ekaj: not being an expert, I haven't heard "address" used in this respect. One thing I can say though is that "address" implies a qualified location, where "offset" is a relative location. ("123 main street" is an address, "next door" is an offset) – horatio Apr 19 '12 at 17:25
@briankip : 16 bytes = it's arbitrary. We hardly use the number 10 when we're dealing with binaries and so on, we tend to use 8 or 16, since they are power of 2. And the number 16, when represented in hexadecimal, is written 10 :) In hexadecimal, you have (...)08,09,0a,0b,0c,0d,0e,0f,10,11(..) – woliveirajr Apr 1 at 17:09
