Specifying a Data Set Name
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.memoFor 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)When you press the Enter key on the Data Set Utility panel, you see the Allocate New Data Set panel with various data set attributes as data entry fields. What you type in these fields depends on what you want the attributes to be and whether or not the data set is sequential or partitioned. Generally, the information that appears in the fields is left from the last allocated data set.
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 ALLOCATEDAn 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)
