Here is the entire, very explanatory config.txt file that someone customized for XY4 in vDosPlus. I am guessing it is by Wengier Wu, but someone has done all the heavy lifting. If you install Edward Mendelson's vDosPlus-Mac, and go to Preferences you can see one that offers to edit config.txt. Use Mac's text editor, paste in this config.txt (or just use the actual settings and cut the explanations in rem), and use my key assignment for Alt-C from previous email to use Alt-C for cut from XY to clipboard (the LPT 4 line in config.txt) and control-V for paste into XY. Change LINS to 25 for the standard XY window. I also edited autoexec via Preferences to add: CD XY (or whatever the name of your full XY4 directory is)ed.bat So when you click on the vDosPlus-Mac app you go directly to XY4. -----------------################################### vDosPlus XyWrite 4.03 ################################### #[Note that this config.txt file is designed for vDosPlus XyWrite 4.03. It contains settings not present in previous versions. Each vDosPlus XyWrite installer run prepares a new config.txt file compatible with the currently installed version.
