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 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, %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.

Famous quotes containing the word language:
“Strange goings on! Jones did it slowly, deliberately, in the bathroom, with a knife, at midnight. What he did was butter a piece of toast. We are too familiar with the language of action to notice at first an anomaly: the ‘it’ of ‘Jones did it slowly, deliberately,...’ seems to refer to some entity, presumably an action, that is then characterized in a number of ways.”
—Donald Davidson (b. 1917)
“The world does not speak. Only we do. The world can, once we have programmed ourselves with a language, cause us to hold beliefs. But it cannot propose a language for us to speak. Only other human beings can do that.”
—Richard Rorty (b. 1931)
“Public speaking is done in the public tongue, the national or tribal language; and the language of our tribe is the men’s language. Of course women learn it. We’re not dumb. If you can tell Margaret Thatcher from Ronald Reagan, or Indira Gandhi from General Somoza, by anything they say, tell me how. This is a man’s world, so it talks a man’s language.”
—Ursula K. Le Guin (b. 1929)
