>Yes, but indirectly - you could call an out-of-process server, for example. if all I needed were lightweight comms in the background and I weren't running anything processor-intensive, MSCOMM32 could probably handle it in conjunction with VFPCOM to link VFP code to the OnComm event, but it's still a single thread of execution; VFP wouldn't interrupt a single atomic VFP command (for example, a horrible non-optimizable query) to execute an event handler; it only responds to events between lines of code...

Right, but that's as close as we can get in VFP.
