Compiler Mode

│ Deutsch (de) │ English (en) │ español (es) │ suomi (fi) │ français (fr) │

The Free Pascal compiler will compile in a specific mode. Each mode dictates what syntax the compiler accepts as valid, and what it considers as invalid. The compiler mode can be set in the source code with the {$mode } compiler directive, or on the command line with the -M option.

• Free Pascal: {$MODE FPC}
  This is the original Free Pascal compiler mode. It is the default mode of the compiler, so it is not necessary to explicitly add this directive.

• Extended Free Pascal: {$MODE OBJFPC}
  This mode adds extra functionality to the FPC mode, including classes, interfaces and exceptions.

• Turbo Pascal: {$MODE TP}
  This is the Turbo Pascal compatibility mode.

• Delphi: {$MODE DELPHI}
  This is the Delphi compatibility mode.

• Mac Pascal: {$ MODE MacPAS}
  The Mac Pascal compatibility mode.
