      The paper considers the issues of converting (transforming) textual commands into tabular commands in the form of data structures. The convertor implemented in one file system is described. The issues of the command text analysis – syntax checking, setting the withhold values for missed operands (parameters), checking operands for belonging to tolerance region, as well as the issues concerning the construction of tables corresponding to commands are considered. The descriptions are used in the converting process to analyze a command and construct a table. The development of such descriptions is an easy to implement process, as compared to the program convertor modification.
