TclPro Debugger works not only with standard Tcl applications such as tclsh and wish , but also with CGI applications, remote applications, and Tcl interpreters embedded in other applications.
Product highlights Simple graphical interface.
TclPro Debugger displays your source code in a window where you can simply click on lines to set breakpoints. When your application stops, the current line is displayed along with a stack trace and values of local variables. With TclPro Debugger you can set breakpoints that cause the application to stop whenever a particular line of code is executed or whenever a particular variable is modified. Once the application is stopped, you can step through commands one at a time or continue the application at full speed. You can choose either to step through or step over nested procedures.
