	##**Option()**## allows the programmer to specify additional attributes or characteristics.  Enclosing the string into quotes and parentheses is required in the syntax.  Unrecognized options are ignored.

	##**Option**## can also be used as a statement to specify other compile time options.  See [[CatPgCompilerSwitches Compiler Switches]].

	Individual options are explained below.

{{fbdoc item="subsect" value="SSE"}}
	##**Option("SSE")**## indicates that a floating point value (##[[KeyPgSingle Single]]## or ##[[KeyPgDouble Double]]##) returned from a function is stored in the ##xmm0## register.  ##[[KeyPgOption Option("SSE")]]## is ignored unless the source is compiled with the [[CompilerOptfpu -fpu SSE]] command line option.  This option may be used immediately after the return type in a function declaration or function definition.  This option is an optimization only and not required to compile programs using the [[CompilerOptfpu -fpu SSE]] command line option.

	%%(freebasic)
declare function ValueInXmm0 () as double option("sse")

{{fbdoc item="subsect" value="FPU"}}
	##**Option("FPU")**## indicates that a floating point value (##[[KeyPgSingle Single]]## or ##[[KeyPgDouble Double]]##) returned from a function is stored in the ##st(0)## register.  This option may be used immediately after the return type in a function declaration or function definition.

	%%(freebasic)
declare function ValueInStZero () as double option("fpu")
