It's a good programing practice to have error handler in place in your application. It helps with runtime errors debugging tremendously. Take a look at article 'Error handling in VFP' by Doug Hennig at http://stonefield.com/techpap.html an the error handler project at http://www.ideaxchg.com/ix07/er/_sys/toccontu.htm.
