Syntax
── ? ─┬─────────────┬──────────────────────────────────────────────────% └─ " ──<text>─┘
Explanation
The ECHO function echoes <text> back to the terminal. When the defined control character, which is usually a question mark (?), is entered without text, a number sign (#) is returned. This command may be useful in verifying correct operation of a terminal.
Example
?"HELLO DOWN THERE "HELLO DOWN THERE ? #
