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 Procedural Programming for details on more advanced constructs, such as `BEGIN ... END `

statements, **For **and **While **loops, local variables and assignments.
