[Fractint] Old formulas

I am trying to do some long overdue organizing and have come across a bunch of parameter files that call for the cubeg2_ma formula. In my mail archive the message with them has no date or name. It is close to other posts from the year 2000. It makes reference to the formula being in a previous post. One that I don't seem to have. The formula is not in the Orgform collection. I can't make the Fractint archives display anything before this year. The formula cubege_ma is supposed to be in the cubeg2.frm file. Does anyone have a clue? Charles
