Issue/Introduction

 We noticed when running SARBCH when we specify the  /PRINT DDNAME=SAROUTA to UNIT=TAPE  vs when we specify it as UNIT=DISK, that running against DISK is taking a lot more resources to complete.

Resolution

SO04100 (14.0) and SO04101 (12.2) have been built and published. 
These change the BLKSIZE= parameter for the batch jobs to BLKSIZE=0,
which uses the System Determined Blocksize (SDB) and makes the utilities more efficient.
