You may have inherited the "j" loop counter from me.  I stopped using 
"i" in loop counters and started with "j" because most code (variables 
and keywords) do not use words with the letter "j" or "k" in them.  On 
the other hand, A LOT of variables and keywords have "i" in their names. 
  The result is that it is a PAIN to find loop variable references for 
the loop variable "i" but it is usually trivial to find them for "j" and 
"k".

Case in point: how many "i"s does your loop have?  Just in the for() 
loop control line, I count five.

Trivia:
* I find I almost never need to nest loops more than 2 deep, so "j" and 
"k" cover almost all loop variable needs.

* I believe Fortran coding conventions started the "ijk" counter mania.
