basic.operators

Relational Operator/BASIC Program, Releases: AP and R83

Operators * ! & = # - + / ^ < > \ [ ] ( )

Description

Operators are reserved characters (and combinations of adjacent characters): * ! & = # - + / ^ < > \ [ ] ( ) and may be referenced individually by their respective symbol.

Expressions are formed by combining operators with other expressions.

When an expression is encountered as part of a Pick/BASIC program statement, it is evaluated by performing the operations specified by each of the operators on the adjacent operands.

Each operator has a precedence rating and, in any given expression, the highest precedence operation is performed first. (0 is the highest precedence and 8 is the lowest). If there are two or more operators with the same precedence or if an operator appears more than once, the leftmost operation is performed first.
