Test functions

	The test functions are logical operators that always return
	either a 1 (true) or a 0 (false).
<	Less than. Returns 1 if true, 0 if false.
	value1<value2
≤	Less than or equal to. Returns 1 if true, 0 if false.
	value1≤value2
= =	Equals (logical test). Returns 1 if true, 0 if false.
	value1==value2
≠	Not equal to. Returns 1 if true, 0 if false.
	value1≠value2
>	Greater than. Returns 1 if true, 0 if false.
	value1>value2
≥	Greater than or equal to. Returns 1 if true, 0 if false.
	value1≥value2
AND	Compares value1 and value2. Returns 1 if they are both
	non-zero, otherwise returns 0.
	value1 AND value2
IFTE	If expression is true, do the trueclause; if not, do the
	falseclause.
	IFTE(expression, trueclause, falseclause)
	Example
	IFTE(X>0,X2,X3)
NOT	Returns 1 if value is zero, otherwise returns 0.
	NOT value
OR	Returns 1 if either value1 or value2 is non-zero, otherwise
	returns 0.
	value1 OR value2
