If you are creating a dialog window, you can specify presentation parameters inside the dialog template. For any window in a dialog template (including the dialog window itself) you may add one or more PRESPARAMS statements to the template following the definition of the control.
Note: For the dialog window, place the PRESPARAMS statement immediately after the DIALOG statement in the template.
