system statement   statement



Syntax:
system ExistingType nameOfConstVarOrMacro [, nameOfConstVarOrMacro2...]

Description:
In FutureBasic version 4 and prior, this was a synonym for the end statement; In FutureBasic version 5 onwards, it no longer serves that purpose. Now it is used, mainly in Headers files, to declare macros and extern constants in Carbon or other frameworks.

Example:

Taken from headers:
system CFDictionaryKeyCallBacks kCFTypeDictionaryKeyCallBacks
system CFBooleanRef kCFBooleanTrue
system CFBooleanRef kCFBooleanFalse

General:
system double INFINITY
print INFINITY
stop
