RENAME Attribute

Specifies a new name for the symbol in the output object, either as a string literal, or with a MATCHREF expression. When a MATCHREF expression is used, substrings from the original name can be substituted from a MATCH expression used to specify the symbol_name. The MATCHREF substitution tokens for the name use the identifier character n, and are of the form {$nN}. See MATCH and MATCHREF Expressions.
