An operating system created by IBM. It should replace DOS, but lost the race on the PC to Microsoft Windows. Windows NT 3 shared some code with OS/2, it even had the same cryptic error messages. * A port of Tcl 7.3, except for glob or command pipelines, to OS/2 2.x using C Set++ has been done by mailto:wwb@wwa.com (Bud Bach). As of this date, I have no leads on anyone porting Tk to any version of OS/2. There are some OS/2 X client support kits available for purchase, which might make it easier to port Tk. * A Tcl/Tk port for OS/2 can be found at: http://hobbes.nmsu.edu/h-browse.php?dir=/pub/os2/dev/tcl. <> Operating System
