A pipe is just a filter, you bung data in one end, it does some transformations on that data, and bugs it out the other. Of course, the in and out can also be pipes. Under 7.0, you can create a background only application. That is, one that has no (or little) interface, and runs entirely in the background. You drop a data file on the application, and it can do its stuff. It could produce another data file at the end, or it could invoke another faceless application with the output. Sounds like a pipe to me. So which software company is working on pipes ? And how about a graphical interface to put together an arbitrary sequence of pipe applications ? I hear the chime of the cash register already. maurice -- Maurice Sharp MSc.
