If you've got an extended period of time where you're not performing any sort of console input, occasionally you'll see situation where Windows complains that a program has stopped running (Windows doesn't like it if a program doesn't perform console I/O for an extended period of time). If you've got heavy processing going on, you're probably going to get this there have been some occasions where in the midst of a processing loop I'd placed an occasional call to DOEVENTS -- so that form events (such as one for a STOP button that I'd put on a form) could be processed (note than each time DOEVENTS is processed, there will be a slight delay, so overall it does tend to slow processing down). Of course, this could only be done if the processing is occurring within a loop that is in VFP code. If the long-running process is a query or an external program, you're probably not going to have an opportunity to insert a DOEVENTS in the loop process.
