  4. Abbreviations used in parameter names
  5. Why links are not working in Portuguese based Windows



When you start WaNuLCAS
Open the Excel file, answer “yes” on whether or not to enable macros
Open the Stella file, wait for it to load and answer “yes” on whether or not to establish links
Back

When you quit WaNuLCAS
Close the Stella file (save if you want)
Close the Excel file (save if you want)
Before you save your Stella file, you might want to clear graphs and tables (button on the main menu) in order to save time and KB.

Do NOT rename the wanulcas.xls file (if you do, the link to Stella will not work).

If you want to distinguish one file from another, use separate folders for them instead.

Why links are not working in Portuguese based Windows

This is the explanation we get from Stella Customer Service.

"... When DDE links are created from excel, you'll notice in the Link Editor that the link is designated as "R3C5" or something to that effect, which stands for Row 3 Column 5 in the Excel spreadsheet. Only problem is that in Portuguese, "Row" is "Lina," so if you create the link on a Portuguese computer, you see "L3C5" instead. For this reason, if you create the link on a US computer, and try to email it to somebody in another country, it may just not work. The universal antidote to this, regardless of Regional Settings, is to give the export cells a Name in Excel (insert/name/define command), and then manually change the "R3C5" in the Ithink Link Editor to the name of the cell or cell range. This is good practice anyway, since you can then move the linked cell around the spreadsheet as you edit it, and not screw up the link... "

See this document for more information.

For users experiencing this problem, we provide a special version of WaNuLCAS which can only be opened using Stella version 6 or above.
