It is not good programming practice to perform the read/write the way you describe but the following will fix it (yes, you need both "close" statements)

Code:
BEGIN{FS=OFS="|"; myfile = "for_later.txt"}
{
    sub("line ","",$2)
    print $0 > myfile    # at this stage of the script I redirect the output that I will need later
}
{
    close(myfile)
    while( (getline < myfile) )   # here I redirect the produced file to keep processing it
    print $0 FS "Price:   $"
    close(myfile)
}

Thanks a lot scottaazz !

I can understand the first "close" but I would never think about the second one !

Beware, by using the changes suggested by scottaazz, you'll only have the latest record from your input file/s in for_later.txt

Seems to work well for me.

But yes I understand why I should not use that systematically.
