Here's what I was using back in FPD2.6 to avoid that. It was about replacing something for all line items in a document. The date on the file is 30-nov-1997.

	Goto _slzaizm
	_vrklj=eval(_dokje)      && vrednost ključa - key value, dok je - while
	Seek _vrklj
	Calculate min(recno()), max(recno()) to _prvisl, _poslsl;       && first, last
		while _vrklj=Eval(_dokje)
		_oldord=val(sys(21))           && we didn't have tagno() then
		Set orde to 0
		Goto _prvisl
		Scan Next _poslsl - _prvisl+ 1 For _vrklj=Eval(_dokje)
			Select Sklop
			Gather Memvar Memo Fields Mat    && this is generated code, could have multiple fields here
		EndScan
		Set Order To _oldord           && restore tag
		GoTo _slzaizm            && go to the record to change
