So if I specify my data set as VB it can contain empty records, but if I specify it as VBS, it can't (couldn't)? Still makes no sense. I could imagine prohibiting an empty segment _except_ as the only segment of an empty record, but even for that I see no reason. Sigh. Was the null segment in VBS invented (partly) to deal with the problem of noise record processing on tapes? Lacking the null segment, one couldn't write a valid tape with containing a data set containing only one record where that record has only one byte of data. More boundary condition concern. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
