Yes, it has to be after DE record and before the first record that doesn't belong to DE. You can use

INSERT BLANK
Here's excerpt from FPD 2.6 help:
INSERT [BEFORE] [BLANK]

Inserts a new record into the current table/.DBF immediately
after the current record and displays the new record for
editing.

Or you can do something like

* Position pointer on the record after wich you want to insert new record
...
lnTempFile = SYS(2015)
SKIP
lnRecno = RECNO()
COPY REST TO (lnTempFile )
GOTO ( lnRecno )
DELETE REST
* APPEND or INSERT new record
...
APPEND FROM (lnTempFile )
PACK
ERASE (lnTempFile )

I hope, you would do this on the copy of the SCX. :)
