You can make it work though by wrapping your script this way:

1) at the beginning put a "$!N" command

2) at the end put a "P;D" command (that's actually a P and a D)

3) execute the script with "sed -n".

This works only if you want to examine two lines at a time and if your 
substitution commands do not change the number of new-lines (i.e. they 
change 2 lines to 2 lines).
