BLKSZ — Block size (number)

For all processing of non-VSAM data sets, and reporting on VSAM components with SCAN REALVOLS, REPORT COMPONENTS, the value of BLKSZ is set to the value of the field DS1BLKL in the Format-1 DSCB for each data set or component.

For all other processing of VSAM clusters, the value of BLKSZ is set to the physical block size field PHYBLKSZ or the CI size field AMDCINV in the catalog record for each VSAM cluster, depending on the value of sysparm VSUSEBLK. For more information, see the sysparm description for VSUSEBLKn in the Systems Guide.
