Ok now i am trying to understand ... Smilie

1) is s=p=$1 equivalent to p=$1; s=p
or is it equivalent to s=p ; p=$1 ?

2) I don't get why the p is mandatory : i have tried to run the following :

Code:
# nawk -F\| 's!=$1 OFS $2{if(s)print s t; t=x; s=$1 OFS $2}{s=s OFS $4; t=t OFS $5}END{print s t}' OFS=\| infile
