Re: the last instance of a record

Rick, 
You don't mention if rpg is an option or not.
If it is, you could do the following: 
I'm assuming that duplicate keys are in rrn order.
The f-spec would specify to open the file in key sequence. 
read file-name;
dow not %eof(file-name);
setgt key-field(s) file-name;
readpe key-fields(s) file-name;
// logic goes here to do whatever you want with the found record
read file-name;
enddo;

I've got a file with 2 or 3 years worth of history in it.  the key
fields are not unique, so duplicates abound. I want to extract the last instance (by rrn) of each key value. will this work? copy the file (by rrn) to a sequencial file (this ?might? not be necessary?) create an empty duplicate file with unique keyword specified. cpyf to the empty file using *UPDADD 
sound kosher?
