Not true. If you code a DCB macro without a BLKSIZE, the blocksize field in the DCB is left as zero. That is not the same as specifying zero, but it has the same effect. Likewise, if no BLKSIZE is specified in the JCL, the value in the DCB remains zero. This allows SDB to be used for a new data set, or the block size in the VTOC or tape label to be used for an existing data set. -- 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
