Apple II manual Statement SYNTAX/FUNCTION DIM, Statement SYNTAX/FUNCTION END

	FNJ7, FNKO, FNR2. User defined func-
	tions are restricted to one line. A function
	may be defined to be any expression, but
	may only have one argument. In the
	example, B and C are variables that are used
	in the program. Executing the DEF state-
	ment defines the function. User defined
	functions can be redefined by executing
	another DEF statement for the same
	function. "V" is called the dummy variable.
	Execution of this statement following the
	above would cause Z to be set to 3/B+C,
	but the value of V would be unchanged.
STATEMENT	SYNTAX/FUNCTION
DIM	DIM variable (size 1, [size 2...])
	Allocates space for matrices. All matrix
	elements are set to zero by the DIM
	statement.
	Matrices can have from one to 255
	dimensions.
	Matrices can be dimensioned dynamically
	during program execution. If a matrix is
	not explicitly dimensioned with a DIM
	statement, it is assumed to be a single
	dimensioned matrix of whose single
	subscript may range 0 to 10 (eleven
	elements).
	If this statement was encountered before a
	DIM statement for A was found in the
	program, it would be as if a DIM A(10)
	had been executed previous to the execu-
	tion of line 117. All subscripts start at
	zero (0), which means that DIM X(100)
	really allocates 101 matrix elements.
STATEMENT	SYNTAX/FUNCTION
END	END
	Terminates program execution without
	printing a BREAK message. (See STOP.)
	CONT after an END statement causes
	execution to resume at the statement after
	the END Statement. END can be used
	anywhere in the program, and is optional.
STATEMENT	SYNTAX/FUNCTION
FOR	FOR variable = expression to expression
	[STEP expression] (See NEXT statement)
	V is set equal to the value of the expression
	following the equal sign, in this case 1. This
	value is called the initial value. Then the
	statements between FOR and NEXT are
	executed. The final value is the value of the
	expression following the TO. The step is
	the value of the expression following STEP.
	When the NEXT statement is encountered,
	the step is added to the variable.
	If no STEP was specified, it is assumed to
	be one. If the step is positive and the new
	value of the variable is <= the final value
	(9.3 in this example), or the step value is
	negative and the new value of the variable

100 Z=FNA(3)
