VB data sets have RDWs; VBS data sets must have SDWs. It's irrelevant(1) that the SDW for a single-segment nonempty logical record in a VBS data set is identical to the RDW of a logical record with identical content in a VB data set. VBS data sets have only SDWs, not RDWs (read carefully; I'd be delighted to be persuaded otherwise), and by specification the minimum count in an SDW is 5.
(1) Even as the occurrence of the word "six" in French text is a French word, not the similar English word; nor does this generalize to allowing arbitrary use of English words in French writing. L'Académie française would insist otherwise. Thanks for the citation. And I've given you a rare opportunity to disagree with Shmuel and me simultaneously. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
