Using ISPF to allocate and edit a data set

The following instructions explain how to use ISPF to allocate a data set, edit it, and place your JCL control statements in it.

Note: ISPF screens may differ slightly from one MVS™ installation to another.

On the ISPF Primary Option menu, select the appropriate item to display the Data Set Utility menu.

On the Data Set Utility menu, select Option A (allocate new data set) and enter a data set name as shown in step 3 below, replacing userid with your own user ID.

----------------------------  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              M - Enhanced data set allocation

ISPF LIBRARY:
   PROJECT ===>
   GROUP   ===>
   TYPE    ===>

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

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

On the Allocate New Data Set menu, fill in the fields indicated in the example below, replacing volser, unit, and size with appropriate values according to the information you filled in on Installation conventions worksheet.

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

DATA SET NAME: userid.SORT.JCL

   VOLUME SERIAL      ===> volser      (Blank for authorized default volume) *
   GENERIC UNIT       ===>             (Generic group name or unit address) *
   SPACE UNITS        ===> unit        (BLKS, TRKS, or CYLS)
   PRIMARY QUANTITY   ===> 1           (In above units)
   SECONDARY QUANTITY ===> 1           (In above units)
   DIRECTORY BLOCKS   ===> 0           (Zero for sequential data set)
   RECORD FORMAT      ===> FB
   RECORD LENGTH      ===> 80
   BLOCK SIZE         ===> size
   EXPIRATION DATE    ===>             (YY/MM/DD, YYYY/MM/DD
                                        YY.DDD, YYYY.DDD in Julian form
                                        DDDD for retention period in days
                                        or blank)

   ( * Only one of these fields may be specified)

Note that message "DATA SET ALLOCATED" indicates that the allocation has been completed.
```

Use ISPF to edit the allocated data set and enter the JCL control statements into the data set.
