On z/VSE,
LIOCS limits are 32768. PIOCS limits are 65536 (which we use on tape, a lot). Off hand, I don't know if PIOCS supports 64K on DASD or not.

Not sure why I typed DOS. I meant z/VSE. Sorry


From a vtoc (two different files) where I was trying to move some data
from VSE to z/OS:
  >
RECFM   BLKSIZE Created  Expires
DSORG   LRECL       YYYY.DDD YYYY.DDD
SAM VBS 56660 32768 2016.339 2016.339




Interesting. So, I wonder why the did not make the limit 65535, since this is 
the maximum number that can be represented in an unsigned haldfword.
