The following example illustrates the DASDL syntax for the data set physical options:

D DATA SET
 (
  A ALPHA(10);
  B BOOLEAN;
  E UNORDERED DATA SET
   (
    F FIELD(15);
    N NUMBER(S9,2);
    X ALPHA(20);
   )
    ALLOCATE FROM END,
    POPULATION = 10,
    EXTENDED = TRUE,
    PACK = SITEPACK;
 )
  AREAS = 100,
  AREASIZE = 1000 RECORDS,
  BLOCKSIZE = 10 RECORDS,
  BUFFERS = 2 + 2 FOR EACH USER,
  KIND = DISK,
  LOCK TO MODIFY DETAILS,
  EXTENDED,
  SECTIONS = 3;
