I'd go with your earlier suggestion that QSAM should report as a data error any SDW of 0004xxxx other than 00040000, and return a no-data record for the latter. The reporting mechanism must exist. What does QSAM do on encountering an RDW/SDW with count exceeding BLKSIZE? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
