I was thinking that Scott might reply so I waited until he did to tell you
what I have done in this situation. My requirements are that the first
"record" has a field that has a count of "records" in the file. So I don't
have that number until I write my last bit of stream data. What I decided
to do was to generate two stream files, one that would contain the first
header "record" and another to contain all the rest of the detail data. The
program does it's processing, outputs the second file, and accumulates the
"record" count. At the end of the process I create the file with the first
header "record" with the "record" count, close and open the file with all
the other detail "records", read and append those "records" to the header
file, close both files, and unlink the detail file. Check out Scott's IFS
tutorial for all the information you need.
