A source listing file is also created. Other file types with the same file name are not deleted. The directives are listed and discussed alphabetically. An optional str-lit is displayed on the terminal screen and in the compilation listing, if a listing has been requested. Lex-var is the name of a lexical variable.
Lexical variables are always LONG integers.
Lex-var must be enclosed in parentheses. It must not be a keyword or a compiler directive. Replacement-token may be an identifier, a keyword, a compiler directive, a literal constant, or an operator. The replacement-token is substituted for every subsequent occurrence of the macro identifier in the program text. A macro-id cannot be used as a line number.
