Subparameter definition
- LIBRARY
- Specifies a partitioned data set extended (PDSE). A PDSE can contain either program objects or data members, but not both. LIBRARY uses the PDSE_VERSION parameter in IGDSMSxx or its default to determine which version of PDSE to allocate.
- (LIBRARY,1)
- Specifies a version 1 partitioned data set extended (PDSE). A PDSE version 1 can contain data and program object members.
- (LIBRARY,2)
- Specifies a version 2 partitioned data set extended (PDSE). A PDSE version 2 can contain data and program object members. Version 2 offers more efficient directory usage.
- HFS
- Specifies an HFS data set. Specify HFS only when the DD statement also specifies a DSNAME parameter.
- PDS
- Specifies a partitioned data set (PDS). A PDS can contain data and load module members.
- PIPE
- Specifies a FIFO special file. Specify PIPE only when the DD statement also specifies a PATH parameter.
- EXTREQ | (EXTREQ,1) | (EXTREQ,2)
- Specifies for the data set to be extended format if the data set is VSAM or sequential, or if DSORG is omitted from all sources. (EXTREQ,1) specifies a version 1 extended format data set. (EXTREQ,2) specifies a version 2 extended format data set. If the data set is not striped and has multiple volumes, the system uses FlashCopy for the data set. EXTREQ specifies for the system to select version 1 or 2 based on the PS_EXT_VERSION parameter in the IGDSMSxx member of SYS1.PARMLIB. The default value for PS_EXT_VERSION is 1.
- EXTPREF | (EXTPREF,1) | (EXTPREF,2)
- Specifies for the data set to be extended format if the data set is VSAM or sequential, or if DSORG is omitted from all sources. If extended format is not possible, the system selects basic format. (EXTPREF,1) specifies a version 1 extended format data set. (EXTREQ,2) specifies a version 2 extended format data set. If DFSMSdss is used to copy a version 1 extended format data set that is not striped and has multiple volumes, the system cannot use FlashCopy for the data set. If the extended format data set is version 2 and FlashCopy is available, the system can use FlashCopy. EXTPREF specifies for the system to select version 1 or 2 based on the PS_EXT_VERSION parameter in the IGDSMSxx member of SYS1.PARMLIB. The default value for PS_EXT_VERSION is 1.
- LARGE
- The system will select large format if the data set is sequential (DSORG=PS or PSU) or DSORG is omitted from all sources and the data set is not VSAM.
- BASIC
- The system will select basic format if the data set is sequential (DSORG=PS or PSU) or DSORG is omitted from all sources and the data set is not VSAM.
