OKCancel is using the internal page named "WEBDEVOKCancel". To include this page in your project:
  1. Select "File .. New .. Page".Click among the quick access buttons. Click "Page" in the wheel that is displayed. The window for creating a new element is displayed: click "Page" then "Page".
  2. In the "Internal page" tab, select the internal page named "OK/Cancel".Click "Internal page" in the wizard and select the internal page named "OK/Cancel".
  3. Validate. The "WEBDEVOKCancel" page is displayed in the editor.
  4. Save the page by keeping its default name.

Line break in the dialog box

CR (Carriage Return) can be used to force a break to the next line. For example:
IF OKCancel("Caution: you are going to delete this record" + CR + ...
"Do you want to continue?") THEN
HDelete(CUSTOMER)
END
is equivalent to:
IF OKCancel("Caution: this record will be deleted", ...
"Do you want to continue?") THEN
