Jim,
You can indeed still use /rnr in Excel to reset all range names just
like in Lotus 1-2-3 without the need for a special macro or function.
1.) Do the menu sequence Tools>Options, then in the resultant dialog
box, click the Transition tab.
2.) In the "Microsoft Excel Menu of Help Key" field, enter a /, then
choose the "Lotus 1-2-3 Help" radio button and click OK.
3.) Now from your worksheet, hit just the / key on the keyboard to
bring up "Help for Lotus 1-2-3 Users" dialog box.
4.) Click the "Demo" radio button, then click the "Faster" button until
the number reaches 5 and click OK.
5.) From now on, simply do /rnr to reset all your range names. (Note
that while Excel performs this for you, it will be showing you a "demo"
by going through all the screens for you. Don't worry about that -
just let it happen; Excel will indeed be performing /rnr for you.)
By the way, now that you'd set this up, you will find that most (but
not all) Lotus 1-2-3 "/" commands will now work in Excel, and as you
type them, you actually see the old Lotus 1-2-3 menu sequences appear
on screen.
Let me know if this was a help to you.
