I am employed by Case Western Reserve University [L1 ] and work at the Cleveland Functional Electrical Stimulation Center [L2 ], a biomedical engineering R&D consortium.
I use Tcl for internal projects, including PC-based user interface software for embedded controllers, and for test suites for the controller hardware and firmware.
Ported Tcl 2.1 to MS-DOS sometime between 1990 and 1992. Used Tcl lightly in the mid-90's, mostly for CGI scripting. Since 1999, most of my programming has been in Tcl/Tk.
