I didn't know whether to post this here or on the Snow Leopard forum. Since the question involves using files designed to run on non-Leopard Macs, I decided to put it here. Back in the not so good old days, Excel 4/Mac was a very helpful application. I'm not a programmer at all, but I was able to learn how to use Excel's Macro sheets. I designed a three-sheet set comprised of two sheets involved in calculating formulae for chemical reactions and a third, Macro sheet, that performed operations for and on the other two sheets. It took me over a month to put it together, but it was able to produce formulae in one or two seconds that would take a full working day to accomplish by hand. For me, it was a treasure. Then, Microsoft abandoned the Macro sheet in favor of VisualBasic and/or RealBasic. That move put me out of the Macro business. I was able to get the sheets to continue to work together using Excel 2004, but I had no resources to produce new Macro sheets or to substantially edit existing sheets. I'm in the process of trying to rewrite the two other sheets to accomplish the same goals without using the Macro sheet, but the going is slow and the result lacks the breadth of function that the old arrangement had. Has anyone else had a similar experience? Is there any way to continue to use the now long-abandoned Macro sheet in the modern environment? I still have the original floppy disks used to install Excel 4, but I doubt that they would be usable on Snow Leopard. Thanks in advance for any help or advice you can give.
