Syntax level variant settings by version

The Eiffel Software compiler provides a set of options, available in Project Settings, which allows users to select a variant of the Eiffel programming language syntax that best suits their needs. The meanings of these options, and in fact the options themselves, are subject to change from one version to the next. Below you will find a table that defines the meaning of the syntax level variants for each version.

The options are distinguished by how the compiler handles the processing of certain words found in Eiffel text which may be:

1. Associated with language constructs, or
2. Allowed as identifiers, or
3. In the case of some options as either keywords or identifiers depending upon the context in which the words are found.

* A general explanation of what each variant setting means can be found in the section on setting the syntax variant.
