Temporary VSAM

Allocation:

Temporary VSAM data sets can be allocated by specifying RECORG=KS/ES/LS/RR (RECORG keyword is the dynamic allocation parameter) along with other parameters of DD statement as follows:

1.      Syntax for temporary KSDS:

//SORTVSAM     EXEC PGM=SORT

//SYSOUT          DD  SYSOUT=*                                   

//SYSPRINT        DD  SYSOUT=*

//INDD1             DD  DSN=&INFILE,DISP=SHR

//OUTDD1          DD  DSN=&&OUTFILE,DISP=(,PASS),                     

//                             RECORG=KS,SPACE=(CYL,(25,50),RLSE),             

//                             LRECL=4000,AVGREC=K,KEYLEN=11,KEYOFF=0            

//SYSIN              DD  *

    SORT FIELDS=COPY

//*

Where:

LRECL=(Maximum record size), KEYLEN=(KSDS key length), KEYOFF=(KSDS key location), STORCLAS=TEMP

2.      Syntax for temporary ESDS/LDS/RRDS:

RECORG=ES/LD/RR,LRECL=(Record length), STORCLAS=TEMP

Restrictions:

1. Multivolume temporary VSAM data sets is not permitted.
