#posId := POSITION xmlfile [* | positionString]
Create a new position identifier for the selected element of the XML file xmlfile. If an asterisk is passed, or if positionString is empty, an identifier, unique to this xmlfile, is automatically generated.
Such a position works as a pointer to an element of the XML file. It can be used with the command
SET xmlfile POSITION as well as with many macro commands in the classes BDataSet, BStxIni and BXMLDoc.
Note that positionString may not contain a simple integer since it would interfere with internal indexing. If a simple integer is specified as the position string, it will be replaced with a unique identifier.
