Hi Adrian
sorry about the confusion and thanks for the explanation.
In terms of the second issue, not being able to compile programs with both XLSAdapter and XLSXAdapter, I will try to find what might be incorrectly installed or defined for paths. It is really not a big issue though as I can always replace all XLSAdapters with XLSXAdapters and everything else works now that I know to set only one SaveFormat (whichever is appropriate to the spreadsheet template and output I want).
As always, thanks for the excellent support.
Bruce
