{{fbdoc item="title" value="Intrinsic Defines"}}----
Preprocessor symbols defined by the compiler.

{{fbdoc item="desc"}}
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.

**{{anchor name="PLATFORM|Platform Information"}}**
Defines that provide information on the system.
**{{anchor name="VERSION|Version Information"}}**
Defines that provide information on the ##**fbc**## compiler version being used.
**{{anchor name="CMDLINE|Command-line switches"}}**
Defines that provide information with the command-line switches used with ##**fbc**##.
**{{anchor name="ENVIRONMENT|Environment Information"}}**
Defines that provide information about the operating system environment.
**{{anchor name="CONTEXT|Context-specific Information"}}**
Defines that provide context information about the compilation process.
