I started tcl programming in the windows 3.11-days, after a long period of hard DOS-programming tasks... I'm usually writing system-scripts and sometimes userprograms with Tk-GUIs. Other used languages are PowerBasic for windows or REXX. Still surprised by the power and elegance of tcl/tk, and the improvement of the development productivity. Unfortunally, most of the chiefs haven't ever heard about tcl/tk...
My (constantly neglected) personal homepage is here: http://www.freewebs.com/hoffnung/ . If I find time, I will post code fragments in other languages than tcl/tk there.
