We are in z/OS 1.4 and SMS active. > System Determined Blocksize apparently chooses a blocksize based on RECFM, LRECL, and the type of the device. For some device types, apparently, IBM has fixed this, piecemeal, device by device. See, for example, OW46399. If similar concerns apply to DUMMY, you should try for an APAR. It should be considered a design objective of SDB to supply a valid BLKSIZE whenever the programmer omits it.
This could happen very subtly, for example when the program has RECFM and LRECL coded in the DCB for SYSPRINT, but BLKSIZE defaulted. Such a program will will work if JCL supplies DSN= for SYSPRINT, or SYSOUT= (at least after OW46399), then suddenly fail if JCL supplies DUMMY. -- gil -- StorageTek INFORMATION made POWERFUL ---------------------------------------------------------------------- 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
