ALLOCATE a data set

The ALLOCATE command can be used to allocate PDS, PDS member, GDG, temporary data set, similar new dataset, PS, PDS/E, etc.

Examples:

Creating PDS with following parameters

  • Record length: 80
  • Record format: Fixed
  • Space: 2 cylinder for both primary and secondary allocation
  • Directory blocks: 10
ALLOCATE DATASET(#dsname) NEW DIR(10) CYLINDERS SPACE(2,2) DSORG(PO) RECFM(F) LRECL(80) BLKSIZE(80) CATALOG

To allocate PDSE specify DSNTYPE(LIBRARY). We don't have to specify DIR here. Anyway, it's PDSE. The system will ignore it.

ALLOCATE DATASET(#dsname) NEW CYLINDERS SPACE(2,2) DSORG(PO) DSNTYPE(LIBRARY) RECFM(F) LRECL(80) BLKSIZE(80) CATALOG

Creating PS with following parameters

  • Record length: 80
  • Record format: Fixed Blocked
  • Space: 2 cylinder for both primary and secondary allocation
ALLOC DA(#dsname) DSORG(PS) SPACE(2,2) TRACKS LRECL(80) BLKSIZE(800) RECFM(F,B) NEW

Creating a data set using LIKE

Allocate a new file #dsname2 which has similar properties as the file #dsname1 with a different space parameter which is 4 for primary and 2 for secondary (overriding some parameters).

ALLOC DA(#dsname2) SPACE(4,2) TRACKS LIKE(#dsname1)

ATTRIB for an ALLOCATE command

ATTRIB specifies a list of attributes. So then we can use it for a data set allocation. List remains for the duration of the TSO session or until explicitly released with FREE command.

ATTRIB TESTATTR LRECL(80) BLKSIZE(80) RECFM(F) DSORG(PO) 
ALLOC DA(#dsname) USING(TESTATTR) NEW CYLINDERS SPACE(2,2) DSNTYPE(LIBRARY) CATALOG
FREE ATTRLIST(TESTATTR)

RENAME a data set

RENAME #old_name #new_name

DELETE a data set or a data set member

To delete a data set with help of TSO command, type:

TSO DELETE '#dsname'

The shorthand of DELETE is DEL.

Note: it's better to provide a data set name within the quotation mark ''.

SMCOPY a data set

You can copy a data set to either a new or existing data set

With SMCOPY we can copy:

  • a PDS member into another PDS or PDS/E
TSO SMC FDS(#pdsname1(#mem)) TDS(#pdsname2(#mem)) NOTRANS
  • a PDS member into a sequential data set
TSO SMC FDS(#pdsname(#mem)) TDS(#sequential_data_set) NOTRANS

Note: you can specify the line numbers that interest you by adding the keyword LINE(n:m), for instance, LINE(3:6) will copy 3, 4, 5, 6 records of a data set
