Required RECYCLE JCL Data Definition (DD) Statements

The following are required RECYCLE JCL Data Definition (DD) statements:

JOB

The JOB statement.

STEPLIB

The STEPLIB DD statement specifies the CA Vtape authorized program library.

EXEC

The EXEC DD statement or execution statement specifies the program to be executed and program parameters that invoke the CA Vtape RECYCLE Utility. Specify PGM=SVTRCYCL, PARM='START=SVTRC100, SVTS=SVTn', where SVTn is the name of the SVTS system identification name that is accessed by the RECYCLE Utility. The program parameter, START=SVTRC100, informs the RECYCLE Utility to execute REXX member SVTRC100, which resides as a member of the data set defined by the SYSEXEC DD statement.

SYSEXEC

The SYSEXEC DD statement defines the CA Vtape REXX content library used by the RECYCLE Utility.

SYSTSIN

The SYSTSIN DD statement defines the REXX procedure language command input file. CA Vtape REXX routines do not access or require the functions provided by the SYSTSIN DD statement; therefore, specify the SYSTSIN DD statement as DD DUMMY,DCB=(BLKSIZE=80).

SYSTSPRT

The SYSTSPRT DD statement defines the REXX procedure language message processing output file. CA Vtape and SORT informational messages are written to this DD statement when the RECYCLE control statement, SET DEBUG, is defined as a RECYCLE Utility input command parameter. REXX file I/O services requires the SYSTSPRT DD statement to be allocated to a JES SYSOUT data set.

Data set attributes are DCB=(LRECL=121,DSORG=PS, RECFM=VBA). The DCB BLKSIZE parameter is defined as multiple of LRECL plus 4‑bytes for the Block Descriptor Word (BDW). For example DCB=(BLKSIZE=1214). DCB attributes are provide by REXX and are not required to be specified when defining the SYSTSPRT DD statement.

SYSPRINT

The SYSPRINT DD statement defines the CA Vtape RECYCLE Utility log data set. RECYCLE control statements and informational status messages are written to the SYSPRINT DD statement. The SYSPRINT DD statement defines a physical sequential data set, a member of a partitioned data set, or a GDG data set. The SYSPRINT DD statement DCB attributes are defined by the RECYCLE Utility program. The RECYCLE Utility program defines the SYSPRINT DCB attributes are DCB=(LRECL=137,DSORG=PS,RECFM=VBA, BLKSIZE=4114).

REPORTS

The REPORTS DD statement defines the CA Vtape RECYCLE Utility output report file. RECYCLE output reports and informational status messages are written to the REPORTS DD statement. The REPORTS DD statement defines a physical sequential data set (DASD, TAPE), a member of a partitioned data set, or a GDG data set.

The REPORTS DD statement DCB attributes are defined by the RECYCLE Utility program. The RECYCLE Utility program defines the REPORTS DCB attributes as follows:

DCB=(LRECL=125,DSORG=PS,RECFM=VBA). You may define a BLKSIZE DCB attribute using the following formula: BLKSIZE=((n*LRECL)+4).

SYSUTn

The SYSUTn DD statements define CA Vtape RECYCLE Utility work files. All DCB attributes for the SYSUTn DD statements are defined by the RECYCLE Utility program. The RECYCLE Utility program defines the DCB attributes as follows:

DCB=(LRECL=256,DSORG=PS,RECFM=VB). Do not define DCB attributes when defining the SYSUTn DD statements. The RECYCLE Utility program dynamically changes the SYSUTn DCB attributes during execution of the REXX procedure modules during RECYCLE.

SYSUTn DD statements are not permitted to be allocated to TAPE or GDG data sets and are only permitted to be defined with a disposition (DISP) of DISP=(NEW,SHR, or OLD). DISP=MOD is invalid and will result in an error message.

SORTWKnn

The SORTWKnn DD statements define CA Vtape RECYCLE Utility internal sort work files.

Data set attributes are defined by the respective CA Sort program products.
