Greg,

Coding the DSORG is best practice for SDB. Omitting BLKSIZE or coding
BLKSIZE=0 is user preference.

Simply removing BLKSIZE or changing to BLKSIZE=0 is common practice, but it
is not good practice. This is why SDB was not used for Ron's a Seq
allocation examples.

This is not good practice:

//DD1      DD SPACE=(TRK,(5,1)),RECFM=VB,LRECL=80

And neither is this

//DD1      DD SPACE=(TRK,(5,1)),RECFM=VB,LRECL=80,
//            BLKSIZE=0
