Carl, that looks terrific. One question only: Can the three PRN and PR4 files go into the PRINTER folder instead of the top-level folder? In my experiments, this path requires in SETTINGS.DFL paths like these: PRINTER\STANDARD.PRN but I wonder whether that will work if the user changes the default directory, or for other reasons. Using your work, I’ve put together a system for Windows that runs XyWrite 4 under DOSBox-X and opens a file that’s dropped on the application. I’ll fiddle with it for a while before posting.
