Is there a point beyond Hex 11 where Hex numbers turn to alphabet again? Do the hex numbers continue in decimalline form beyond hex 11? That is , 12,13,14,... http://img139.imageshack.us/my.php?image=hexrv9.jpg

Hmm, let me just count a little for you in hex: 0, 1, 2, 3..., 8, 9, a, b, c, d, e, f, 10, 11, 12, ..., 18, 19, 1a, 1b, 1c, 1d, 1e, 1f, 20, 21, etc. Does this make sense to you now?

To continue on that line of reasoning: the hexadecimal number system (normally just written hex), is just base 16. Since we don't have 16 distinct numerals (that is, characters which represent numbers), we borrow the first 6 Latin letters: 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f,10,... Just like any base, 16^1 = 10, 16^2 = 100 so the number 2af means 2 *16^2 + a*16^1 + f*1 = 2*256 + 10*16 + 15 = 512 + 160 +15 = 687 in base 10
