REPROREPRO ParametersBefore you begin: Be familiar with the following information before using REPROparameters:vvvvvvvPartial copying of linear data set clusters is not permitted. The entire linear dataspace must be copied. A linear data set cluster can be copied to or from aphysical sequential data set if the control interval size of the linear data set isequal to the logical record length of the physical sequential data set.REPRO cannot be used as source or target tape data set if the blocksize is largerthan 32760 bytes.Attributes of data sets created by REPRO follow the same rules as those createdby the JCL or by other utilities. Specifications of blocksize, logical record length,and blocking factors must be consistent with the type of data set and its physicalcharacteristics. For more information, see the following documentation:– z/OS MVS JCL Reference– z/OS MVS JCL User’s Guide– z/OS DFSMS: Using Data SetsBecause REPRO does not copy the control information stored in the directories,program libraries (in either the PDS or PDSE format) should not be copied.While the PDS as a whole cannot be copied, individual PDS members can becopied.If you want to copy a KSDS that is larger than 4GB to a system that does notsupport extended addressability, you must use the FROMKEY and the TOKEY,or COUNT parameters to reduce the size of the data set or to create severalsmaller data sets.If you use the REPRO command to copy compressed files, the record countinformation is not provided and message IDC005I is not displayed.REPRO copies the records of a VSAM recoverable data set. However, the locksused for VSAM record-level sharing (RLS) are not transferred. For the correctprocedure to use when copying or moving data sets with pending recovery, see“Using VSAM Record-Level Sharing” in z/OS DFSMS: Using Data Sets and CICSRecovery and Restart Guide.The REPRO command uses the following parameters:Required ParametersINFILE(ddname[ ENVIRONMENT(DUMMY)])|INDATASET(entryname[ ENVIRONMENT(DUMMY)] )Identifies the source data set to be copied. If the logical record length of anon-VSAM source data set is greater than 32760 bytes, your REPRO commandwill end with an error message. The keys in the source data set must be inascending order.INFILE(ddname)specifies the name of the DD statement that identifies the data set to becopied or the user catalog to be merged. You can copy a base cluster inalternate-key sequence by specifying a path name as the data set name inthe DD statement.Abbreviation: IFILEINDATASET(entryname)specifies the name of the entry to be copied or user catalog to be merged.If INDATASET is specified, the entryname is dynamically allocated with a306 z/OS V1R6.0 DFSMS Access Method Services for Catalogs
