I can fully agree to what Dale said, concerning unique range-names within a worksheet.
After this I tried the same as a sample in Excel 97:
1. created a worksheet (Sheet A) - named cell C3 as "myname" - and then made a short
calculation with this name into cell A5
2. created a 2nd sheet (Sheet B) - and copied all the contents from Sheet A to Sheet B.
Indeed - when I looked into the formular of cell A5 of sheet B I found again a the
reference-adress "myname" - but - and that is very important: all you do is, that you
reference to the SAME adress as you did in sheet A - so when you have a "5" there in
sheet A, also sheet B will use this contents ("5"

.
If that is all you want, then you could create a worksheet A in Lotus, but only use
ABSOLUTE adresses (e.g. $myname) there - which will then be hold when you copy it to
Sheet B up to all sheets after B.... if you want.
I can not imagine that a new EXCEL can do it other- this would make all prior worksheets
in Excel not compatible and make it confusing to know, which worksheet is meant when you
refer to e.g. myname.
