Defines the block size of the file.

If RECFM=F, the LRECL must match the BLKSIZE parameter.
If RECFM=FB, the BLKSIZE must be a multiple of the LRECL.
If RECFM=U, CA XCOM Data Transport ignores this parameter.
For F or FB data sets, allowable LRECL values are 4‑32760 bytes.
For V and VB files, allowable values are 4‑32756 bytes.
For FBA and VBM, allowable values are from 5‑32756 bytes.
For V, VB, VBA and VBM files, the LRECL must be at least 4 bytes less than the BLKSIZE.
For VBS and VS, allowable values are 256‑32767 bytes.
For VS and VBS, the LRECL can be larger than the BLKSIZE.
