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:
“In a language known to us, we have substituted the opacity of the sounds with the transparence of the ideas. But a language we do not know is a closed place in which the one we love can deceive us, making us, locked outside and convulsed in our impotence, incapable of seeing or preventing anything.”
—Marcel Proust (1871–1922)
“Repeat thy song, till the familiar lines
Are footpaths for the thought of Italy!
Thy flame is blown abroad from all the heights,
Through all the nations, and a sound is heard,
As of a mighty wind, and men devout,
Strangers of Rome, and the new proselytes,
In their own language hear thy wondrous word,
And many are amazed and many doubt.”
—Henry Wadsworth Longfellow (1809–1882)
“It is silly to call fat people “gravitationally challenged”Ma self-righteous fetishism of language which is no more than a symptom of political frustration.”
—Terry Eagleton (b. 1943)
