раздел данных(Data division is used to define the variables used in the program. It consists of four sections − File section is used to define the record structure of the file. Working-Storage section is used to declare temporary variables and file structures which are used in the program. Local-Storage section is similar to Working-Storage section. The only difference is that the variables will be allocated and initialized every time a program starts execution. Linkage section is used to describe the data names that are received from an external program.)
