Intrinsic Defines
Preprocessor symbols defined by the compiler.
Description
Intrinsic defines are set by the compiler and may be used as any other defined symbol. Intrinsic defines often convey information about the state of the compiler, either in general or at a specific point in the compilation process. Most intrinsic defines are associated with a value.
Platform Information
Defines that provide information on the system.
Version Information
Defines that provide information on the `fbc` compiler version being used.
Command-line switches
Defines that provide information with the command-line switches used with `fbc`.
Environment Information
Defines that provide information about the operating system environment.
Context-specific Information
Defines that provide context information about the compilation process.
Constants
Built-in constants.
