OFS = Output Field Sparator (default is space)
ORS = Output Record Separator (default is new line)

OFS and ORS what do they signify
The OFS (output field separator) and ORS (output record separator) built-in variables give you more flexibility.
You may need to modify the output like this, for example*:

Code:
zsh-4.3.11[t]% awk '{
  for (i = 1; ++i < NF;)
    printf "%s", ($i (i < NF - 1 ? OFS : ORS))
  }' OFS=, ORS='\n=========\n' infile
2,3
=========
B
=========
YY,ZZ,AA
=========

* Note that the multi-character RS/ORS is GNU awk specific.
