What does LRECL mean when RECFM=U? I found this in DFSMS Using Data Sets under the heading 3.2.3.1.2 System-Determined Block Size <quote> DASD Data Sets: When you create (allocate space for) a new DASD data set, the system derives the optimum block size and saves it in the data set label if all of the following are true: Block size is not available or specified from any source. BLKSIZE=0 can be specified. You specify LRECL or it is in the data class. The data set does not have to be SMS managed. You specify RECFM or it is in the data class. It must be fixed or variable. You specify DSORG as PS or PO or you omit DSORG and it is PS or PO in the data class. .... The system does not determine the block size for the following types of data sets: Unmovable data sets Data sets with a record format of U </quote> -- Tom Marchant ---------------------------------------------------------------------- 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
