Visual DialogScript
Visual DialogScript (VDS) is an interpreted programming language for Microsoft Windows, using dialog and graphic elements to create programs. VDS is similar to other programming languages such as Visual Basic, C++, or Delphi, as they use Windows API. Language Unlike other programming languages, the syntax of VDS is very simple. Each command occupies one line and has a plain English name that clearly describes its purpose. Variables are typeless and can hold many kinds of information, for example, numbers or text. Functions are clearly distinguishable with names that start with '@', just like a spreadsheet. The DialogScript language has a simple syntax, not unlike the MS-DOS batch language. It is designed for ease of use and efficiency when being interpreted by the run-time engine. There are 10 system variables, %0 to %9, which initially have the script file name in %0 and command line parameters in %1 through %9, just as in a batch file. There are also a further 26 user variables, from %A to %Z. The contents of all variables (including system ones) can be changed once the script is running. There are now also 4032 global variables. These variables begin with %%, a letter, then alphanumerics plus underscores (e.g., %%my_variable_1.) There is no limit on the length of these user-defined variable names. Syntax examples Comments: # This is a single line comment REM This is a single line comment Simple Information Message Box: info "This is the information text" Simple Warning Message Box: warn "This is the warning text" Create a custom dialog box: dialog create,<name>,<top pixel position>,<left pixel position>,<width in pixels>,<height in pixels> Write to the Windows Registry: registry write,<root key>,<key>,<subkey>,<data> Display an input prompt dialog box, storing the result in the variable %A: %A = @input("Please enter a value:") History Visual DialogScript was created by Julian Moss (1953 – October 24, 2014) of JM-Tech/Tech-Pro Ltd. In 1998, after version 3.0, Emmanuel Daunizeau of S.A.D.E. sarl, took over the ownership and development of VDS, modifying and improving its syntax. Currently, VDS is marketed by the British company Commercial Research Ltd. and is still the property of Emmanuel Daunizeau who; continues to develop it. Several versions of VDS have been released over time: Visual DialogScript 2.0 Visual DialogScript 2.5 Visual DialogScript 3.0 Visual DialogScript 3.5 Visual DialogScript 4 Visual DialogScript 4.5 Visual DialogScript 5 Visual DialogScript 5.01 Visual DialogScript 5.02 Visual DialogScript 6 Currently available versions There are several versions available for download: Personal Visual DialogScript (PVDS) 4: This freeware version is intended for students and home PC users. The package includes a short tutorial and full online help, which includes many example scripts. The software is not licensable for commercial use. This version is incapable of producing compiled executable files; however, compiling files is not necessary, as a script file can be executed directly by opening it from Windows Explorer on any system that has PVDS installed on it. Visual DialogScript 2.5 (16-Bit Edition): This version marked the last release for Windows 3.1+ (16-bit). Visual DialogScript
