Display the OK, Cancel, and Help buttons, plus an error message. DCL Error Handler Tile
This error handler tile displays the OK, Cancel, and Help buttons, along with an error message (if necessary) at the bottom of a dialog box. It is useful to have the Help button call the LISP help function.
Notice that the format of this tile differs from most other tiles: there is no : (colon) prefix nor { ... } (brace) suffix.
The program pre-assigns a key to each button, as follows:
| Button | Key |
|---|---|
| OK | "accept" |
| Cancel | "cancel" |
| Help | "help" |
| errtile | "error" |
