It's a twelve-byte entry with name of all X'FF' and a TTR value of zeros. Benjamen, ISTR that a RECFM=U, LRECL=255,KEYLEN=8 brought in a key as well as the actual block. It's been so long that I may have been using BSAM,but SQAM sticks in the mind. Oh well, it's been so long that it really matters not, at this point. <G> Rick (Retired) Fochtman --- Why didn't Noah swat those two mosquitos? --- [This E-mail has been scanned for viruses by the YourNet Connection Virus system] [For more information, please go to http://www.ync.net/YourMAIL] ---------------------------------------------------------------------- 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
