There aren't any rules.  The results of using FMTDTA without sorting are 
not guaranteed to be in FIFO order.  My experience with tagalong sorts 
is extensive and I can say that in general, you get FIFO results.  I 
believe I have had records placed out of FIFO order in the past though.

If this were my task, I'd use OVRDBF MBR(*ALL) if I had to process all 
the members, and CRTLF if I had to process a subset.  If I had to 
process a dynamic subset, I'd write a utility to do the CRTLF.
