Indeed, my thesis is that Tcl and Tk's problems primarily stem from economic and marketing (human) factors, rather than any serious defects with the technology itself. Starting with a clear picture of the basics, Tcl/Tk covers the variety of tools in this “Swiss army knife” of programming languages, giving you the ability to enhance your programs, extend your application's capabilities, and become a more effective programmer. Before we go further, I want to This meant that fewer tasks could be accomplished via scripting languages, but a scripting language that let you write routines in C, or, conversely, let the main C program execute bits of script code from time to time was a very sensible idea. It's king of the world when it comes to building graphical user interfaces (GUIs) for C programs (particularly those running in X Windows environments), which is what the language originally was invented to do. Tcl/Tk (which is Sections cover basic and advance programming techniques, specific aspects of Tk widgets, and extending the C library that defines Tcl. The Tcl scripting language and the Tk toolkit together create a programming environment for creating graphical user interfaces. Mismatches between the operations available in the formal code (which supports a limited set of allowed meanings) and the informal users (which can generate unlimited interpretations of the program) are a major source of user errors. These features are extended by a large .. Data handling and storage facility; operators for calculations on arrays and matrices; a large set of tools for data analysis; graphical facilities for data analysis and display; a well-developed, simple, and effective programming language. My current research interests are mainly in Applied Statistics, but I also work as system manager, net manager, web developer and programmer (C, C++, FORTRAN, Php, Tcl/Tk). Copious examples make it easier to understand (and quickly employ) effective design strategies. Newly updated with over 150 pages of material on the latest Tcl extensions, Tcl/Tk: A Developer's Guide is a unique practical tutorial for professional programmers and beginners alike. Currently the program should be able to handle well scans that have their text in one column and do not have tables.
