Names for Individual Operands
An individual operand, meaning an operand that is not an expression, can be elementary or made up of components. Composite operands are:

Structured data types or data objects (structure)

Instances of classes (objects)

Classes

Interfaces

Accordingly, names for operands are either elementary names or names constructed from multiple names separated by component selectors. An elementary name is used for addressing:

elementary operands

components that are unique in the current context

superunits made up of components

Naming conventions apply to the elementary names. Composite names with component selectors are used for addressing individual components. A component can itself be a superunit of further components. Subcomponents can be addressed by chaining multiple names.

As well as the component selectors listed here, Open SQL has a column selector ( ~ ).
