: dialog {
initial_focus label value
}
A dialog is the tile that defines the dialog box. You should not specify both a label and value attribute: the value attribute overrides the label attribute.
Specifies the optional title displayed in the title bar of the dialog box.
Specifies a string to display as the optional dialog box title. However, the value isn't inspected at layout time, so if you assign the title this way, make sure the dialog box is wide enough or the text might be truncated.
For a dialog, the label and value are equivalent except for layout considerations. To change the title (see in at runtime, use the set_tile function the AutoLISP Reference).
Specifies the key of the tile that receives the initial keyboard focus.
