Re: Update primary filre

Oh man, am I going to hate myself for this.

You want to use LOOKAHEAD in your i specs.  The lookahead field gives 
you the fields you are interested in before you actually read the 
record.  That way you can Look ahead" and see if the next record is in 
this set or the next set.


I haven't used lookahead for 30+ years, but its probably still available?
