The only line that I have trouble understanding is this one:
if row[0].empty?

I try to logically think about it.  Lets say it hits a spill-over line 
and it has to process the string "C22,C23,C26,C27".  So it chomps it at 
divides it up by tabs, which there are none because the chomp removed 
them if there were any.  So, now row is a one element array.  At this 
point I think row[0]="C22,C23,C26,C27" and row[1]=nil, row[2]=nil. 
Where is my logic flawed?

Whats the difference between chomp and strip.  I've only been using 
strip.

Thanks again.
