I am having some trouble closing a spreadsheet.
The included Perl opens a spreadsheet, reads the first two cells and then tries to close it.
As the copy of the contents of the MSDOS screens shows, the variable to be set when the workbook is
closed is not set but no error is reported. Can someone explain why this is and how to get a ‘1’ for the
result of closing the workbook?
