[screen-pt]])

Arguments

dlgname

A string that specifies the dialog box.

dcl_id

The DCL file identifier obtained by load_dialog.

action

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.
