Unrelated question, Fabio.
Do you know the simplest way to find out all changed fields using GetFldState result without using AT function?

Here is a code where I'm using in a similar method. I'm wondering, if this code could be simplified:

	lcFieldState = SUBSTR(GETFLDSTATE(-1),2) && The first character returns deletion status
	lnOccurance = 1

	lnPos = AT('2', m.lcFieldState, m.lnOccurance)

	DO WHILE m.lnPos > 0
		DO CASE
		CASE !FieldChanged(FIELD(m.lnPos))

&& not changed
		CASE INLIST(UPPER(FIELD(m.lnPos)), UPPER("cLast_Updated_User"), ;
				UPPER("tLast_Updated_Date"))

&& ignore
		OTHERWISE
			REPLACE cLast_Updated_User WITH ;
				IIF(VARTYPE(m.gcUserID) == "C", m.gcUseriID, getuserid()), ;
				tLast_Updated_Date WITH DATETIME()
			lnPos = 0
		ENDCASE
		IF m.lnPos > 0
			lnOccurance = m.lnOccurance + 1
			lnPos = AT('2', m.lcFieldState, m.lnOccurance)
		ENDIF
	ENDDO
