There is a way to do it now.

When you execute RREPORT with the -i[n] (where [n] is the letter 
denoting the index) you can move within the file using a LOOKUP -.

What I do is a build an index that allows me to move to the beginning of 
the records I want to select and then, once I'm past them, I lookup to a 
record past the end of the file to end quickly.

::INPUT aa(8,mdy/) "Enter starting date: "
::INPUT ab(8,mdy/) "Enter ending date: "
::LOOKUP - k=ba  i=A -ng

Skip this lookup after the first record.

After the selection line do a check to see if the records are now past 
the ending date.
: 1 gt ab
:: LOOKUP - k="12/31/2200" i=A -ng

I believe it was Nancy Palmquist who wrote about this quite some time ago.
