The following are optional RECYCLE JCL Data Definition (DD) statements:
The DEBUGDD DD statement defines the CA Vtape RECYCLE Utility request log data set. RECYCLE volume requests and informational messages are written to the DEBUGDD DD statement. The DEBUGDD DD statement defines a physical sequential data set, a member of a partitioned data set, or a GDG data set.
The DEBUGDD DD statement DCB attributes are defined by the RECYCLE Utility program. The RECYCLE Utility program defines the DEBUGDD DCB attributes as follows:
DCB=(LRECL=137,DSORG=PS,RECFM=VBA, BLKSIZE=4114)
The DD that defines an 80-character sequential data set or partitioned data set (PDS) member containing the Exclude Physical Volume List (EPVL). The EPVL is a list of physical tape VOLSERs that should not be processed by RECYCLE during simulate or live processing.
The EPVL consists of one physical tape VOLSER per record. The VOLSER can start anywhere between columns 1 and 65 of the record. Nonblank characters coded prior to the VOLSER will turn the record into a comment and the record will be ignored. Comments can be coded in a record after the VOLSER if they are separated from the VOLSER by one blank character.
The PEXCLUDE DD statement, when defined, requires the following DCB attributes:
//PEXCLUDE DD DSN=@PRFIX.@SYSID.@SVTN.PEXCLUDE, UNIT=SYSDA,DISP=(NEW,CATLG,DELETE), SPACE=(CYL,(1,3)), DCB=(LRECL=80,BLKSIZE=n*LRECL,RECFM=FB)
The DD that defines an 80-character sequential data set or partitioned data set (PDS) member containing the Include Physical Volume List (IPVL). The IPVL is a list of physical tape VOLSERs to be processed by RECYCLE during simulate or live processing. Only the VOLSERs assigned to the group number being processed by the RECYCLE command will be included. If RECYCLE GROUP(02),… is coded and the IVPL contains ten VOLSERs, but only one of those VOLSERs is for group 02, only that VOLSER will be selected for processing. The other VOLSERs will be ignored.
The PERCENT and MAXVOLS selection criteria are ignored when a PINCLUDE DD is coded in the RECYCLE JCL.
The IPVL consists of one physical tape VOLSER per record. The VOLSER can start anywhere between columns 1 and 65 of the record. Nonblank characters coded prior to the VOLSER will turn the record into a comment and the record will be ignored. Comments can be coded in a record after the VOLSER if they are separated from the VOLSER by one blank character.
The SVTR190A file (pull list) can be copied to the PINCLUDE file. RECYCLE will recognize the pull list format and read it without the need for any modifications.
The PINCLUDE DD statement, when defined, requires the following DCB attributes:
//PINCLUDE DD DSN=@PRFIX.@SYSID.@SVTN.PINCLUDE, UNIT=SYSDA,DISP=(NEW,CATLG,DELETE), SPACE=(CYL,(1,3)), DCB=(LRECL=80,BLKSIZE=n*LRECL,RECFM=FB)
The SNAPDUMP DD statement defines the CA Vtape RECYCLE Utility memory image diagnostic file. RECYCLE volume requests and informational messages are written to the SNAPDUMP DD statement. The SNAPDUMP DD statement defines a physical sequential data set, a member of a partitioned data set, or a GDG data set.
Data set attributes are as follows:
DCB=(LRECL=125,DSORG=PS,RECFM=VBA). Do not define DCB attributes when specifying the SNAPDUMP DD statement. DCB attributes are defined by the RECYCLE Utility program.
Output File For Physical Input Volume Pull List Records. This DD statement specifies an output sequential data set that defines a list of physical input volume serial numbers selected for RECYCLE.
The SVTR190A output records are produced when running RECYCLE in LIVE or SIMULATE mode. Each record defines one physical volume. The records are written in RECYCLE input mount processing order. Only the first occurrence of a duplicate input volume is written to the Volume Pull List file.
Customers may use the Volume Pull List file contents to automate media management and ensure that volumes representing the Volume Pull List are available for processing before executing RECYCLE in LIVE mode.
This DD statement, when defined, requires the following JCL parameters (the BLKSIZE DCB attribute may be changed to reflect a multiple of LRECL=80).
//SVTR190A DD DSN=@PREFIX.@SYSID.@SVTN.SVTR190A, UNIT=SYSDA,DISP=(NEW,CATLG,DELETE), SPACE=(CYL,(1,3)), DCB=(LRECL=80,BLKSIZE=6160,RECFM=FB)

Output File For Physical Input Volume Status Records.
This DD statement specifies an output sequential data set or member of a partitioned data set. Each record defines one physical volume. The contents of the SVTR190B file represent a Volume Status List that documents which physical tapes were processed.
Volume Status records are written to the SVTR190B file during RECYCLE LIVE mode. The data set contents are written in ascending volume serial number order.
This DD statement, when defined, requires the following JCL parameters.
//SVTR190B DD DSN=@PRFIX.@SYSID.@SVTN.SVTR190B, UNIT=SYSDA,DISP=(NEW,CATLG,DELETE), SPACE=(CYL,(1,3)), DCB=(LRECL=80,BLKSIZE=6160,RECFM=FB)
