sorting

I was reading the OpenOffice forum message boards and saw a question about sorting on more than 3 categories. I haven't joined the forum since I know very little about Basic but thought I'd at least write down my thoughts somewhere. To sort on, say, 5 categories, first sort on the last two then sort the result on the first 3.
Finally, I'm finding that it isn't as hard as I thought to rewrite macros from Visual Basic to OOo Basic. There are a few differences to keep one on one's toes, of course. A few of the provided macro functions are different (like IFF instead of IF for the function). The workbook functions are mostly the same -- except for using semicolons instead of commas to separate elements.
