LININ	Function
Type:
Description:	Linear Test Function: Tests whether an algebraic is structurally linear for a given variable.
	If any two subexpressions containing a variable (name) are combined only with addition and
	subtraction, and any subexpression containing the variable is at most multiplied or divided by
	another factor not containing the variable, the algebraic (symb) is determined to be linear for that
	variable. LININ returns a 1 if the algebraic is linear for the variable, and a 0 if not.
Access:	!°TEST !«LININ	( °is the leftshift of the Nkey).

Input/Output:

		Level 2/Argument 1	Level 1/Argument 2		Level 1/Item 1
		'symb'	'name'	→	0/1
Example 1:	'(X+1)*(Y^2^Z)+(X/(3Z^3)' 'X' LININ				returns 1.
Example 2:	'(X^21)/(X+1)' 'X' LININ returns 0.
	(Although this equation yields a linear equation when factored, LININ tests the equation as
	described above.)
LINSOLVE
Type:	Command
Description:	Solves a system of linear equations.
Access:	Symbolic solve, !Î, PSOLVE, !Ø LIN S
Input:	Level 2/Argument 1: An array of equations.
	Level1/Argument 2: A vector of the variables to solve for.
Output:	Level 3/Item 1: The system of equations, as a list containing the inputs as above.
	Level 2/Item 2: A list of the pivot points.
	Level 1/Item 3: The solution.

Flags: Exact mode must be set (flag –105 clear).

Numeric mode must not be set (flag –3 clear).

LIST→	Command
Type:
Description:	List to Stack Command: Takes a list of n objects and returns each object to a separate level, and
	returns the total number of objects to item n+1 (stack level 1).
	The command OBJ→ also provides this function.
Access:	…µLIST→

Description:	Stack to List Command: Takes n specified objects and returns a list of those objects.
Access:	!°TYPE →LIST			( °is the leftshift of the		Nkey).
	!°LIST →LIST			( °is the leftshift of the		Nkey).
