I would expect problems if the references to a DCB are in different keys. But, then, I would also expect the documentation to discuss the issue.

However, OPEN (SYSPRINT,OUTPUT),MODE=31 Modeset KEY=ZERO CLOSE SYSPRINT,MODE=31 Returns IEA705I ERROR DURING FREEMAIN SYS CODE = 30A-18 CSBROPEN OPEN2 00 IEA705I 00FC1B80 008D2AA0 008D2AA0 00000300 00000188 00006DD8 IEF450I CSBROPEN OPEN2 - ABEND=S30A U0000 REASON=00000018 "18 = The system could not find a private area subpool." Well, I wasn't looking for one, but somehow changing mode from NZERO to ZERO between OPEN and CLOSE caused a problem. BTW, a PUT macro worked fine anywhere after OPEN. No, this is not production code, dangers with key zero, etc, but it is educational.
