We've never used SYS3 (or SYS2,etc.). Products have their own two HLQ. PRDB2, PRTWS, PRISP, etc. for R/O datasets that reside on SYSRES. PSDB2, PSTWS, etc for runtime libraries for the same product. Bart

HLQ to indicate third party software." So new software installs *have* to follow that "rule". (Past installs did not follow such a rule.) I am thinking that this "rule" is really just *his* rule. Opinions? How many other sites follow such a rule? -- Tony Thigpen ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
