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:
“Both the Moral Majority, who are recycling medieval language to explain AIDS, and those ultra-leftists who attribute AIDS to some sort of conspiracy, have a clearly political analysis of the epidemic. But even if one attributes its cause to a microorganism rather than the wrath of God, or the workings of the CIA, it is clear that the way in which AIDS has been perceived, conceptualized, imagined, researched and financed makes this the most political of diseases.”
—Dennis Altman (b. 1943)
“Great literature is simply language charged with meaning to the utmost possible degree.”
—Ezra Pound (1885–1972)
“The angels are so enamored of the language that is spoken in heaven, that they will not distort their lips with the hissing and unmusical dialects of men, but speak their own, whether there be any who understand it or not.”
—Ralph Waldo Emerson (1803–1882)
