OK. I RTFM. "Using Data Sets" confirms that SDB does not operate on
RECFM=U. But why not?
However:
Title: z/OS V1R7.0 MVS Program Management: User's Guide and Reference
Document Number: SA22-7643-04
3.1.3.1 Binder DD statements
* ... Procedures used by the binder to assign block size to a load module
are:
1. If the data set is new:
a. When the DCBS option is not specified
# When the data set is created without a block size, the
block size is
the maximum supported by the access method for that
device type.
I.e. 32760. So I can equally well use BLKSIZE=0 for load module libraries as
for
other data sets. It matters little to me whether BLKSIZE gets set by SDB or by
the binder.
