Yes. If there is a chance that the first field could contain any characters that are special in an extended regular expression, you would need to not only change: sub($1,x) to: $1=x, but also to change the last line to:
Code:
}' OFS=\| input2.txt input1.txt

or add a BEGIN clause to set OFS.

As long as the 1st field is always just numeric characters, your code is perfectly safe.
