DISPLAY messageText {+} {(VmvCode}
messageText The message text. This can include literal text and control sequences.

Using DISPLAY after a select deletes the active list.
| Control Sequence | Effect |
|---|---|
| @(column{,row}) | Positions cursor at the specified screen coordinates. Both parameters must be integers greater than or equal to 0; if greater than the current maximum (set by the most recent execution of the TERM command), the cursor is placed in the right-most column or bottom row as appropriate. If row is omitted, the cursor remains on the current line. |
| @(code) |
Generates an extended cursor addressing or video effects code. The
effects of these codes depends on the
MultiValue video mode,
selected with the V option (default, Reality). All extended cursor
addressing and video effects codes are negative integers. Refer to the DataBasic @ function for details of the codes available in Reality mode. The @ compatibility option lists codes for other modes. |
| @({count}n) | Generates count carriage returns. If count is omitted, only one carriage return is generated. |
| @({count}b) | Generates count bell characters. If count is omitted, only one bell is generated. |
| @(O{.}code) | Generates the character with the specified ASCII code. If code is preceded by a dot (.), it is interpreted as hexadecimal; otherwise it is interpreted as decimal. Valid values are from 0 to 254 decimal (x'00' to x'FE' hex). |
| `command` | Substitutes the result of executing command, which must be enclosed in grave accents (reverse single quotes). |
The following Multivalue video modes are available:
| Value | $OPTIONS Vendor |
|---|---|
