A book is sanctified to the study of receptions and methods of programming in built-in language of "1С : Enterprise" with the use of the components, used for development of configurations "record-keeping", "Operative account" and "Calculation". For the best understanding of logic of programming a structure over of informative base of all three components is brought. Along with initial information about base language constructs and built-in facilities of planning user interface, the methods of renewal of database and means of treatment of external events come into question. Standard receptions are considered programming used for retrofitting of already existent configurations. The charts of constructions of the modules are presented, complete volume of attributes and methods of metadatas with the unique examples of development of configuration "Building services". The mechanism of treatment of external events is described on example of scintiscanner штрих-кода. Errors and difficulties that can arise up in the process of debugging and work of the programs are examined.For 1С-программистов.
