ASSERT is used as a programmer tool to help prevent errors. If the assert evaluates to .F., then a dialog box is displayed. In Christof's example, if tcoption is anything other than character, the error is triggered. It is used here to make sure the parameter is of the correct type. When you distribute your application, you can SET ASSERT OFF and the assert will be ignored.
