SaveDocumentToFile
![SaveDocumentToFile 1:](Images/jpg/13465138699__Web.jpg)
This method saves a JSON document in a file.
A rising edge at the input parameter bExec triggers the saving procedure. The asynchronous process is terminated as soon as the reference bExec is set back to FALSE from the method. When the process ends, the return value of the method indicates for one call whether saving of the file was successful (TRUE) or failed (FALSE).
