Do you mean you have one file that runs up to a certain date, and 
then another file that runs from that date ?

I've been in that situation in the past. What I did was define the 
cutover point (date/time), define variables from both files, and then 
use an IF statement. I can't look up exactly what I had as I've since 
ripped it out - it was long ago and the newer file covers all the 
period I'm interested in.
