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.
In the professional sphere, I use Tcl for numerous internal projects, including PC-based user interface software for embedded controllers, and for test suites for the controller hardware and firmware.
Recreationally, I ported Tcl 2.1 to MS-DOS sometime between 1990 and 1992, and I've hacked around with it at various times since then.
Since 1999, most of my programming has been in Tcl/Tk.
