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 {$mode } compiler directive, or on the command line with the -M command line option.
Modes
- Free Pascal: {$mode FPC}
This is the original Free Pascal compiler mode. As of version 3, 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.
- ISO 7185 Standard Pascal: {$mode ISO}
The ISO 7185 standard compatibility mode. The ISO 7185 standard is also known as Standard Pascal.
ModeSwitch
As of version 2.3.1 of Free Pascal, the {$ModeSwitch} compiler directive has been added to allow features of a compiler mode to be selectively added to the current mode, effectively creating a custom mode. For example:
{$mode FPC}
{$ModeSwitch EXCEPTIONS}Will add exception handling to the FPC compiler mode.
