Attr The top level classes are "attributed", using Attr, meaning that names, expressions and other elements within the syntax tree are resolved and associated with the corresponding types and symbols. Currently recognized warnings include unused-variable, unused-toplevel, shadowed-toplevel, unbound-variable, macro-use-before-definition, arity-mismatch, format, duplicate-case-datum, and bad-case-datum. By convention, bytecode file names end in. If you change the variable compilation-context-lines to an integer value n, these commands scroll the window so that the current error message is n lines from the top, whether or not there is a fringe; the default value, nil, gives the behavior described above.
They are used to allow source code files to access externally-defined functions. The work to analyse the tree and generate class files is performed by a series of visitors that process the entries on the compiler's To Do list. See Windows Runtime Support for more details.
