RE: Line count?

[Jim Langston <jlangston@xxxxxxxxxxx>]

You can't go back up on lines using O specs.

If you read your file C at the same time you read your
file B then that should work for you.

In one instance on another system I had a similar type of
difficulty, where I didn't know what needed to print on
what line 'til I had read through the entire file.  What
I did in that instance is I created a 66 element array
and built the page in the array then when I was done with
the page I for...nexted through the array and printed the
lines.

You don't want to do this if you can help it though, you
are much better served, I think, if you change your program
logic to incorporate you new file.

Jim Langston

Several ideas:
1) Switch to DDS and use the POSITION keyword.
2) Matching record
3) Build the entire page (or section) in an array
4) Go back to the user and simplify the output
5) Use SQL/OPNQRYF to join the records
6) Give the data to the user in PC or HTML form and let them format it

I you get some ideas from this list that might work for you.
