The definition of each variable is an expression, such as

(- B + Sqrt(B^2 - 4*A*B))/(2*A)

An expression can consist of or contain a literal number (including Boolean or date), a text value, an identifier of a variable, an arithmetic expression, a comparison or logical expression, IF THEN ELSE, or a function call, such as Sqrt(B).

See Chapter 21: Procedural Programming for details on more advanced constructs, such as BEGIN ... END statements, For and While loops, local variables and assignments.
