Finding oldest instance of an entity?

Ok, I am pretty sure that the first command will always give you the oldest one. Look at the following modification of my program.

howmany=0
Type whatever
	Field number
End Type

While Not KeyDown(1)
	If MouseHit(1)
		w.whatever=New whatever
		w\number=howmany
		howmany=howmany+1
		Print "new whatever created w/ num"+w\number
	EndIf
	If MouseHit(2)
		For w.whatever=Each whatever
			Print w\number
		Next
	EndIf
	If MouseHit(3)
		w.whatever=First whatever
		Print w\number
		Delete w
	EndIf
	For w.whatever=Each whatever
		w\number=w\number+1
		w\number=w\number-1
	Next
	Delay 1
