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:
“Never resist a sentence you like, in which language takes its own pleasure and in which, after having abused it for so long, you are stupefied by its innocence.”
—Jean Baudrillard (b. 1929)
“And what the dead had no speech for, when living,
They can tell you, being dead: the communication
Of the dead is tongued with fire beyond the language of the living.”
—T.S. (Thomas Stearns)
“There’s a cool web of language winds us in,
Retreat from too much joy or too much fear:
We grow sea-green at last and coldly die
In brininess and volubility.”
—Robert Graves (1895–1985)
