DScript comes with a large number of routines for additional functionality beyond the SQL-like language, for example, to work with INI-files, the Clipboard or prompt for user input.
These routines are all functions, meaning that they are generally to be expected to return a value and accept zero or more parameters when called.
The available routines are grouped into Namespaces and can be used with their fully qualified name, eg INI.Open(...), GUI.ShowMessage(...) and so on.
When describing the syntax for routines, the following data types are available for input and return values.
