In paper we propose the system of automated formation of the list of symbols in scientific works as kind of hybrid language texts, which are presented in the format of Tex. We describe the main system components. To analyze the text, it is suggested to use LL1 grammar. For grammar, terminal and nonterminal sets and a set of rules are defined. The rules for recognizing variables are described. The usage of LL1 grammar allows expanding the system for new characters of mathematical packages and combining the stages of parsing the text and forming a list. The system can be useful for improving the quality of presentation of texts in hybrid languages.
