Seymour's comment about 32K BLKSIZE= values for "load libraries" needs qualification. It is on the mark for traditional PDSs containing load modules. It is off the mark by a factor of 8 for PDSEs containing program objects. They have an imposed block size of 4K, which should not be/need not be mentioned.
The thread started with a discussion of efficient use of DASD. A 32K text record in a PDS takes up less disk space, allowing for block overhead, than 8 4K blocks in a PDSE. The physical block size in a PDSE does not enforce a restriction on a data set block size. If you are asserting that the Binder reverts to a logical 4K size, then the PDSE would at best match, or come out slightly worse than a PDS with a 4K block size, due to design.
