Prod. Prod. 8-) Yes, sure. But my job doesn't leave me any time to work out a good solution except if I take a vacation for it. I might be able to write a wrapper that just copies the data structure provided by the new generic code into local variables, as is done with the current code. Or I might be able to complete a version that is limited to a small number of simultanous commands (ahemm, ONE single command :) which will be made fully functional a few weeks later (famous last words, I know ...) Well, anyway: I know that you can't accept being kept back for too long, and I appreciate the changes you have prepared and hope they'll be intergrated soon. And I know there are dependencies ... I intend to spend a full work on NCR driver issues this weekend, but I can't promise that I'll have a preliminary solution to offer before one or two other week(end)s have passed. Regards, STefan
