However, thinking about it, surely the answer is to let the multitasker do it. The major problem is in busy do-nothing loops - waiting for a key to be pressed or a mouse click for example. What is needed is an algorithm to do this whithout hogging the CPU. Does the event handler in Turbo Vision do this? If not, a better event handler is required. The sort of (pseudo-) code I'm thinking of is: If any event pending handle and return the event else exit Therefore you only handle pending events, and don't wait for them. Is this enough? Are there going to be any problems (missed events for example)? Best Regards, Derek Carr DEREK@DTS.INE.PHILIPS.NL Philips I&E TQV-5 Eindhoven, The Netherlands Standard Disclaimers apply.

It has specific support for yielding time-slices (called idle- loops). Although DOS may not be out until next month, the API is available and supported by Windows (right now). The api is set up such that supporting it does not force incompatibility with other OS's (or add-ons).
