Reply to note from Edward MendelsonFri, 14 Jan 2022 17:10:32 -0500 As I suspected, I went a step too far in integrating U2 into my portable setup. The fix was simply, in XY4.KBD, to restore the Enter key on the main keyboard (scan code 28) to its default assignment, a simple newline. I've updated the ZIP archive: https://xywwweb.ammaze.net/dls/Xy4018-U2.zip What this change (or reversion) means is that you can no longer use the Enter key on the main keyboard to execute U2 routines. That Enter key can still be used to execute native XyWrite commands, as can NumPad Enter, which always had the newline (CrLf) assignment -- meaning that NumPad Enter was always available to navigate the menus in the usual manner. > ... what is SG1908? It's documented in XY4.DLG as "Path to IBM2TIF.EXE". I don't know what that program is, but it's included in the set of Xy4 installation files at xywrite.com (that's "dot COM", not "dot ORG"): http://www.xywrite.com/xy4/xy4supp/xy4_support_files.htm For the sake of completeness, my portable setup now includes files from the xywrite.com Xy4 installation dump that were not previously included. -- Carl Distefano cld@xxxxxxxxxx
