# which-line command

The which-line command puts the current
port number into the Proc primary input buffer. This was used by the
old Proc-version of power-off, which has subsequently
been replaced by a FlashBASIC program.

## Example(s)

```
who.substitute
001 pq
002 oYou are using port #
003 hwhich-line
004 p
005 d
```
