Working with VSAM Datasets using COBOL Program:

We know that there are four VSAM File organizations.

  • SEQUENTIAL              -----    ESDS
  • INDEXED                     -----      KSDS
  • RELATIVE                    -----       RRDS
  • LINE SEQUENTIAL    -----     LDS

Below are the important terms need to remember while working with COBOL + VSAM .
  1. ASSIGN  ( This Keyword is used during mapping between Logical to Physical File )
  2. ORGANIZATION  ( To indicate it is Indexed or Sequential File )
  3. ACCESS MODE ( Sequential, Random and Dynamic)
