Subject: Conceptual Problem: Ambiguity for Names used in Formulas
Dear List members, a recent bug-report [1] on the OOo-site points to a more fundamental problem of ODF, especially of column naming vs named expressions/ranges. [1] http://www.openoffice.org/issues/show_bug.cgi?id=90230 The problem is not bound to the OpenOffice implementation, though I will describe it based on OOo: OOo 2.4 currently supports 65535 columns, therefore: 'ST1' is a valid name (expression, range, ...). However, with OOo 3.0, this limit will be moved upward, so that 'ST1' will be now a valid column [cell]. Ad extremum, IF we consider a very distant future (why not in 10,000 years ;-) ), then any string used currently as name will probably point to a valid column. [IF only string, then the whole column, IF string_number_ then a cell] It is unsafe to assume that the current column limit will be held [or any other column limit], and changing this limit in the future will jeopardise existing names. I propose to enhance the ODF as follows: - names should be marked explicitly as such within formulas - this will allow to unambiguosly identify a name as such in the future - this will be especially improtant, IF the spreadsheet evolves to something basically limtless, when every name will point to a cell/column Sincerely, Leonard -- Super-Aktion nur in der GMX Spieleflat: 10 Tage für 1 Euro.
