Data Division Map

 Data Definition Attribute codes (rightmost column) have the following meanings:
     D = Object of OCCURS DEPENDING    G = GLOBAL                             S = Spanned file
     E = EXTERNAL                      O = Has OCCURS clause                  U = Undefined format file
     F = Fixed-length file             OG= Group has own length definition    V = Variable-length file
     FB= Fixed-length blocked file     R = REDEFINES                          VB= Variable-length blocked file

  • 01 - Explanations of the data definition attribute codes.
  • 02 - Source line number where the data item was defined.
  • 03 - Level definition or number. The compiler generates this number in the following way:
    • First level of any hierarchy is always 01. Increase 1 for each level (any item you coded as level 02 through 49).
    • Level-numbers 66, 77, and 88, and the indicators FD and SD, are not changed.
  • 04 - Data-name that is used in the source module in source order.
  • 05 - Base locator used for this data item.
  • 06 - Hexadecimal displacement from the beginning of the base locator value.
  • 07 - Hexadecimal displacement from the beginning of the containing structure.
  • 08 - Pseudoassembler code showing how the data is defined.
    When a structure contains variable-length fields, the maximum length of the structure is shown.
  • 09 - Data type and usage.
  • 10 - Data definition attribute codes. The definitions are explained at the top of the DATA DIVISION map.
  • 11 - UNUSED-DATA-ITEM was not referenced in the PROCEDURE DIVISION. Because OPTIMIZE(FULL) was specified, UNUSED-DATA-ITEM was deleted, resulting in the base locator being set to XXXXX.
