| Format |
| | Error [item; item... , item; item ...] |
| | item; item... | List of items to print on each line of the error window. Separate multiple items with semicolons. |
| | The error window is removed after the next INPUT or after the next menu item selection. For informational messages, use the MESSAGE statement. To purge the type-ahead buffer and remove the error window without ringing the bell, use the error statement alone without a list of items. |
| | NOTE |
| | Multiple-line error messages can be displayed by separating each group of items by a comma (,). The error window expands in height from the bottom of the screen to contain the multiple lines of data. |
