The ISPF LIBRARY fields are most often used for data sets that have three qualifiers and follow the data set naming conventions. The OTHER PARTITIONED OR SEQUENTIAL DATA SET field is similar to data set specification in line mode TSO/E, and generally is used for a data set with fewer than or more than three qualifiers. For example, to specify data set PROJECT.ONE, which does not begin with your prefix, type:

OTHER PARTITIONED OR SEQUENTIAL DATA SET
    DATA SET NAME ===> 'project.one'

To specify data set PREFIX.FIRST.PROJECT.MEMO, you can eliminate the prefix and the single quotation marks and type:

OTHER PARTITIONED OR SEQUENTIAL DATA SET
    DATA SET NAME ===> first.project.memo

For more information about naming and specifying data sets, refer to TSO/E Data Set Naming Rules and Conventions.

---------------------------------DATA SET UTILITY ------------------------------
OPTION ===> a

    A - Allocate new data set                  C - Catalog data set
    R - Rename entire data set                 U - Uncatalog data set
    D - Delete entire data set                 S - Data set information (short)
    blank - Data set information

ISPF LIBRARY:
    PROJECT ===>  prefix
    GROUP   ===>  test
    TYPE    ===>  data

OTHER PARTITIONED OR SEQUENTIAL DATA SET:
    DATA SET NAME ===>
    VOLUME SERIAL ===>          (If not cataloged, required for option "C")

DATA SET PASSWORD ===>          (If password protected)

To see descriptions of the data entry fields, press the HELP PF key while the Allocate New Data Set panel is displayed. When you finish typing information in the fields, press the Enter key to create the data set. The following example is for allocating a sequential data set.

----------------------------  ALLOCATE NEW DATA SET  ---------------------------
COMMAND ===>

DATA SET NAME:  PREFIX.TEST.DATA

   VOLUME SERIAL     ===>                (Blank for authorized default volume)*
   GENERIC UNIT      ===>                (Generic group name or unit address)*
   SPACE UNITS       ===> blks           (BLKS, TRKS or CYLS)
   PRIMARY QUAN      ===> 20             (in above units)
   SECONDARY QUAN    ===> 10             (in above units)
   DIRECTORY BLOCKS  ===> 0              (Zero for sequential data set)
   RECORD FORMAT     ===> FB
   RECORD LENGTH     ===> 80
   BLOCK SIZE        ===> 3120
   EXPIRATION DATE   ===>                (YY/MM/DD
                                          YY.DDD in julian form
                                          DDDD for retention period in days
                                          or blank)


   ( * Only one of these fields may be specified)

When you press the Enter key on the Allocate New Data Set panel, the data set is created and you see this message in the upper right hand corner of the panel:

DATA SET ALLOCATED

An example of allocation for a partitioned data set is as follows:

----------------------------  ALLOCATE NEW DATA SET  ---------------------------
COMMAND ===>

DATA SET NAME:  PREFIX.TEST.DATA

   VOLUME SERIAL     ===>                (Blank for authorized default volume)*
   GENERIC UNIT      ===>                (Generic group name or unit address)*
   SPACE UNITS       ===> blks           (BLKS, TRKS or CYLS)
   PRIMARY QUAN      ===> 50             (in above units)
   SECONDARY QUAN    ===> 20             (in above units)
   DIRECTORY BLOCKS  ===> 2              (Zero for sequential data set)
   RECORD FORMAT     ===> FB
   RECORD LENGTH     ===> 80
   BLOCK SIZE        ===> 8000
   EXPIRATION DATE   ===>                (YY/MM/DD
                                          YY.DDD in julian form
                                          DDDD for retention period in days
                                          or blank)
