Functions

This section contains the functions and procedures registered with the Velox scripting compiler. Entries include Velox operations, thin adapters around Delphi routines and functions imported from shipped libraries.

Common tasks​

  • Use Conversion, Date & Time, Format, Numeric and String for value transformations.
  • Use Data and Velox for operations tied to the current integration and its data context.
  • Use File, Email, HTTP-related classes, Program Control and similar effectful groups only after reviewing their side effects and failure behaviour.
  • Use Comparison and If..Else when source values may be Null, empty or represented by a Variant.

Important behaviour​

The declaration on each child page is the exact scripting surface, not a promise that every Delphi overload is available. Parameter modes matter: const values are inputs, while var and out parameters can change a caller-owned variable. Functions return a value; procedures normally communicate through side effects or mutable parameters.

An entry can be a wrapper. Its documentation follows that wrapper through helpers and delegated calls to the terminal implementation, including parameter transformations, exceptions, platform behaviour and implementation quirks. Do not infer safety or purity from a name: entries can perform database work, allocate objects, write files, make network calls or update shared Velox state.

Edge cases and quirks​

Only registered declarations are callable. A function available to Delphi code—or a different overload of the same name—can still be unavailable to a script. Variant coercion, locale-sensitive conversion, path handling and exception propagation are entry-specific and are documented on the physical child page.
