# Reference for unit 'objpas'

Objpas - Delphi and objfpc mode system overrides

`uses`
`System;` |  | The system unit

## Overview

The objpas unit is meant for compatibility with Object Pascal as implemented by Delphi. The unit is loaded automatically by the Free Pascal compiler whenever the Delphi or objfpc mode is entered, either through the command line switches -Sd or -Sh or with the {$MODE DELPHI} or {$MODE OBJFPC} directives.

It redefines some basic pascal types, introduces some functions for compatibility with Delphi's system unit, and introduces some methods for the management of the resource string tables.
