Scripting 6.7. Sending a message to another program

To send messages to running programs that use the Praat shell, use `sendpraat` (see Scripting 8. Controlling Praat from another program).

## Security measure

One some platforms it used to be possible to send a message to another running program that listens to a socket, using the `sendsocket` directive. This is no longer possible in Praat version 7.
