IBM TSO/E REXX User Manual page 207

After you name the data set, a panel appears on which you define the attributes
of the data set. Use the attributes recommended by your installation for REXX
libraries, and include the record format (RECFM), record length (LRECL), and
block size (BLKSIZE) from the appropriate system file from the Preliminary
Checklist #5 on page 187. If you are unsure about which system file is
appropriate, use the values from SYSEXEC.
If your installation has no attribute recommendations and you have no attributes
from the Preliminary Checklist, you can use the following attributes on the
ISPF/PDF Allocate New Data Set panel:
