	The calculator is calculating the integral of an equation
	or program. This might take a while.
	A running SOLVE or ∫ FN operation was interrupted
	by pressing Åor ¥.
 	Data error:
		Attempted to calculate combinations or
		permutations with r >n, with non–integer r or n, or
		with n ≥1016.
		Attempted to use a trigonometric or hyperbolic
		function with an illegal argument:
			qwith x an odd multiple of 90°.
			lor iwith x < –1 or x > 1.
			:owith x ≤ –1; or x ≥ 1.
			:lwith x < 1.
 	A syntax error in the equation was detected during
	equation evaluation, SOLVE, or ∫ FN.
 	Attempted to enter an invalid variable name when
	solving an equation.
 	Attempted a factorial or gamma operation with x as a
	negative integer.
 	Exponentiation error:
		Attempted to raise 0 to the 0th power or to a
		negative power.
		Attempted to raise a negative number to a
		non–integer power.
		Attempted to raise complex number (0 + i 0) to a
		number with a negative real part.
 	Attempted an operation with an indirect address, but
	the number in the index register is invalid (			i	≥ 34or
	0 ≤	i	< 1).
	Attempted to take a logarithm of zero or (0 + i0).
	Attempted to take a logarithm of a negative number.
 	All of user memory has been erased (see page B–3).
 	The calculator has insufficient memory available to do
	the operation (See appendix B).
	The condition checked by a test instruction is not true.
	(Occurs only when executed from the keyboard.)
