Quoting from "CG4107-FormulasAndFunctions.pdf" : "Calc can not reference a whole column of unspecified length using A:A or a whole row using 1:1 which you might be familiar with in other spreadsheet programs." This piece of info was not so easy to find. Since other spreadsheet software (in fact, more than one) indeed supports "A:A: and "1:1" references, I thought that either Calc would support it too, or at least would be easier to find that it doesn't. For example, using Calc to open some xls file with such type of references would end up with errors. The xls file itself would open, but there would be no hint about the reason for the "#ref" or "#name" errors (among the possible errors that this type of cell reference would end up with). Regarding a workaround, once the user finds out that the problem is in the type of reference (which is not always evident), then by adding some column (or some row) to the reference would probably avoid the error. Other methods (e.g offset, range names) would be more close to the original range (complete row / column). This workaround is of course not always available, specially when receiving a spreadsheet file from someone else (originally prepared and saved with other programs). I am still wondering if some setting in Calc would (or should) allow for this type of cell reference. For example, by using "Excel A1" instead of "Calc A1" in Calc -> Tools -> Options -> LibreOffice Calc -> Formula -> Formula syntax. There are many different settings that might influence the accepted behavior, and I really don't know / understand the effect of each one (I didn't find any explanation of what each setting really means), so instead of "playing" with each possible combination, I decided to ask here in the ML (and not all of those settings are located in the same place). If this type of cell reference is _completely_ unsupported, perhaps it should be mentioned in the help files (?). I would agree that referencing complete columns or complete rows should be rarely used, and discouraged, but perhaps supporting a formula that already uses it (specially when using or receiving files originally saved with other file formats) is not such a crazy idea. So, is there any combination of settings that would help in this type of cases? [off-topic] BTW, if I may... Having separated mailing lists according to the program (Writer / Calc / Impress / ...) might be more adequate for users, specially since other methods of communication with LibreOffice / TDF are not really effectively working.
