Re: Reason # 9,457,298,284.2 as to why I want to strangle the guy who came up with PREV

["Corey Saxe" <csaxe@xxxxxxx>]

Roy,
You read my mind.
Some interesting things...

A4:=LastValue(C+PREV-PREV);
A2:=Sum(A4,2);
A3:=Sum(LastValue(C+PREV-PREV),2);

A2; {Using LastValue(C+PREV-PREV) in a separate variable negates the locking
effect that LastValue(+PREV-PREV) gives}

A3  {Using LastValue(C+PREV-PREV) within the same equation maintains the
lock}

Evidently, the PREV is associated with the equation which contains it(A3)
and not always the variable(A4) that the PREV is stored in.

Thanks,
-Corey Saxe
