> ' | awk 'BEGIN{OFS=FS="|"}{ for(i=0;i<=NF;i++)

> $i=0
> print $0}'

<Output>

3|300|600|200|700
4|400|800|0|1200

Another one:

Code:
awk '
!f { f2[$1] = $2; next }
f == 3 { f3[$1] = $2; next }
f == 1 { $3 = (f2[$1] ? f2[$1] : 0)
    $4 = (f3[$1] ? f3[$1] : 0)
    $5 = $2 + f2[$1] - f3[$1]
}1' FS="|" OFS="|" file2 f=3 file3 f=1 file1
