(new_dialog dlgname dcl_id [action [screen-pt]])
Arguments
A string that specifies the dialog box.
The DCL file identifier obtained by load_dialog.
A string that contains an AutoLISP expression to use as the default action. If you don't want to define a default action, specify an empty string (""). The action argument is required if you specify screen-pt.
The default action is evaluated when the user picks an active tile that doesn't have an action or callback explicitly assigned to it by action_tile or in DCL.

Return Values
T, if successful; otherwise nil.
