Division symbol. Returns the quotient of two numbers, or the term by term quotient of two lists. For division

of a matrix by a square matrix, returns the left-multiplication by the inverse of the square matrix.

Stores the evaluated expression in the variable. Note that:= cannot be used with the graphics variables G0–

G9. See the command BLIT.

var:=expression

Example:

A:=3 stores the value 3 in the variable A

Strict less-than-inequality test. Returns 1 if the left side of the inequality is less than the right side, and 0

otherwise. Note that more than two objects can be compared. Thus 6 < 8 < 11 returns 1 (because it is true)

whereas 6 < 8 < 3 returns 0 (as it is false).

Less than or equal inequality test. Returns 1 if the left side of the inequality is less than the right side or if the

two sides are equal, and 0 otherwise. Note that more than two objects can be compared. See comment above

regarding <.

Inequality test. Returns 1 if the inequality is true, and 0 if the inequality is false.

Equality symbol. Connects two members of an equation.

Tests for the equality of two lists.

Example:

EQ({1,2,3},{1,2,3}) returns 1

Strict greater than inequality test. Returns 1 if the left side of the inequality is greater than the right side, and

0 otherwise. Note that more than two objects can be compared. See comment above regarding <.
