Transfers a file from the virtual machine context to the front end
        context.
Syntax
fgl_putfile(
   src STRING,
   dst STRING)
- src is the path to the file to transmit from the virtual machine
                    context.
- dst is the path to the file to write in the front end context.
Usage
The fgl_putfile() function downloads a file from the application
 server disk where fglrun is executed to the front-end workstation disk.
Important: Using this function can result in a security hole if you allow the end user
                to specify the file paths without control. There is not limitation on the file
                content or file paths: If the user executing the application on the server side is
                allowed to read critical server files, the program could transfer these files on the
                client workstation. On the other hand, critical files can be written on the client
                workstation. It is in the hands of the programmer to implement file path and/or file
                content restrictions in the programs using fgl_putfile().
