  Creating a physical sequential data set (PS) and partitioned data set (PDS)

  1.     Select 'UTILITIES' option from main menu (shown above). Select option 2 'DATASET'.

  
  
  

  
  

  2.    Type 'A' in OPTION ===> and in ISPF LIBRARY: give the file name with different nodes in different fields. You can also give the whole file name within quotes in  OTHER PARTITIONED OR SEQUENTIAL DATA SET:    DATA SET NAME ===>

  
  
  

  

   

  3.    Basically, the fields on the Allocate New Data Set panel determine data set attributes, such as:

  ·       On which storage device the data set goes (VOLUME SERIAL, GENERIC UNIT). You can leave these fields blank.

  ·       Size of the space (SPACE UNITS, PRIMARY QUANTITY, SECONDARY QUANTITY).

  ·       The amount of space needed for a PDS directory (DIRECTORY BLOCKS). The general rule is one directory block for every six members.

  ·       The kind of records you want in the data set (RECORD FORMAT, RECORD LENGTH, BLOCK SIZE).

  ·       How long you want to keep the data set (EXPIRATION DATE). You may leave this field blank.
