For my application (which consists of converting a delimited ASCII file 
into arrays), a 'line' is an array of fields.  I am using a strscan 
iteration to parse for record terminators and field terminators to 
create a new character array for each field in the line.  These 
character arrays get accumulated into a Ruby array that represents the 
line.  Does this answer you question?
