Opens the specified document.
&DataType.Open(FileName)
Type Returned:
ExcelDocument and WordDocument return a Numeric type; so it is possible to call it as a function (&Err = &DataType.Open(…..)).
For Xml Data types, an ErrCode Data type property is provided for handling errors.
Where:
FileName
Is the path and name of the document. If only the name is specified, the document will be created in the default directory (DataXXX model directory).
ExcelDocument and WordDocument: If the specified document does not exist, it is created by using the template specified in the Template property.
When you open a document with the Open method, it is not displayed on the screen. To show it, you must call the Show method.
XmlWriter: If you do not include the FileName, it is generated by ‘standard output’. When it is a web object it is generated in the response. (It works with CGI, ISAPI, WebClasses and Servlets).
Tip: If you need to know if the spreadsheet already exists you can use file.exists()
