Operatorlevel

Operatorlevel is a term encountered in several technical disciplines to denote a level associated with operators, but there is no single, universally accepted definition. Its precise meaning is domain dependent and can describe either the hierarchy of operators in a language or a layer in a human-centered process control model.

In programming language design and compiler theory, operatorlevel commonly refers to the grouping of operators by precedence and associativity. An operatorlevel comprises all operators that bind at a given precedence; expressions are parsed by applying higher-priority levels before lower ones. Some language specifications label levels numerically, so that operatorlevel 3 would bind stronger than level 2. The term is sometimes used informally in documentation to discuss how expressions should be evaluated or how a parser should be implemented.

In industrial systems and human-computer interaction, operatorlevel denotes the interface level at which human operators interact with a system, distinct from device or control levels. The operatorlevel defines permissions, display content, and control options available to operators, and is often used to structure access control, alarm display, and supervisory functions.

In software engineering and system documentation, operatorlevel may appear as a variable name or field describing the role or scope of an operator within a system. Related concepts include operator precedence, associativity, and human-machine interface architectures.
