You are correct, I apologize for my second mistake in a row. I seem to chime in before taking the time to have my facts straight. I work on that. I once had a problem trying to write to a file that had been allocated with IEFBR14 because the JOB step used BLKSIZE=0. Removing BLKSIZE from the allocation step fixed the problem. Now I normally do not use BLKSIZE at all.

It does no I/O. It issues no SVC. This has been much discussed on this list. o Then, whatever creates the file (I assume it's allocation) does _not_ need a block size, as in the following job step: //STEP EXEC PGM=IEFBR14 //D DD DISP=(,CATLG),UNIT=SYSALLDA,SPACE=(CYL,1), // RECFM=FB,LRECL=80, // DSN=&SYSUID..TEMP.EMPTY ... which leaves visible in Data Set Info: Data Set Information Data Set Name . . . . : user.TEMP.EMPTY General Data Current Allocation Management class . . : **None** Allocated cylinders : 1 Storage class . . . : **None** Allocated extents . : 1 Volume serial . . . : TSO017 Device type . . . . : 3390 Data class . . . . . : **None** Current Utilization Organization . . . : NONE Used cylinders . . : 0 Record format . . . : FB Used extents . . . : 0 Record length . . . : 80 Block size . . . . : 0 1st extent cylinders: 1 Secondary cylinders : 0 Data set name type : Creation date . . . : 2008/08/07 Referenced date . . : ***None*** Expiration date . . : ***None*** worked fine with no block size given. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
