Type: Command
Description: Array to Stack Command: Takes an array and returns its elements as separate real or complex
numbers. Also returns a list of the dimensions of the array.
If the argument is an n-element vector, the first element is returned to level n + 1 (not level nm +
1), and the nth element to level 2.

Type: Command
Description: Stack to Array Command: Returns a vector of n real or complex elements or a matrix of n × m
real or complex elements.
The elements of the result array should be entered in row order. If one or more of the elements
is a complex number, the result array will be complex.
Access: !°
TYPE →ARRY ( °is the left-shift of the Nkey).

Type: Analytic Function
Description: Arc Sine Analytic Function: Returns the value of the angle having the given sine.
For a real argument x in the domain –1 ≤ x ≤ 1, the result ranges from –90 to +90 degrees (–π/2
to +π/2 radians; –100 to +100 grads).
A real argument outside of this domain is converted to a complex argument z = x + 0i, and the
result is complex.
