platform_fbsd can be compared with the value returned by the built-in function platform to determine whether the current platform is FreeBSD (i.e. the interpreter running your program is from the FreeBSD edition of Irie Pascal).
The following simple program displays the current platform.
program ShowPlatform(output);
begin
case platform of
platform_dos: writeln('DOS');
platform_os2: writeln('OS/2');
platform_win32: writeln('Windows');
platform_linux: writeln('Linux');
platform_fbsd: writeln('FreeBSD');
platform_solaris: writeln('Solaris/x86');
platform_solaris_sparc: writeln('Solaris/Sparc');
platform_error: writeln('Unknown Platform');
end
end.
