An expression is a sequence of operators, operands and punctuators that returns a value.

The primary expressions include: literals, constants, variables and function calls.
More complex expressions can be created from primary expressions by using oper-
ators. Formally, expressions are defined recursively: subexpressions can be nested
up to the limits of memory.

Expressions are evaluated according to certain conversion, grouping, associativity
and precedence rules which depend on the operators in use, presence of parenthe-
ses and data types of the operands. The precedence and associativity of the oper-
ators are summarized in Operator Precedence and Associativity. The way operands
and subexpressions are grouped does not necessarily specify the actual order in
which they are evaluated by mikroPascal PRO for AVR.
