More importantly, is it so slow that it impacts your processing unacceptably? CSI is a better approach than reading the output of LISTC, in my opinion, as the LISTC output is not a programming interface. But whatever you do, you may have a TOCTTOU (time of check to time of use) issue. By the time you figure out what the oldest GDG member is, and go to read it, it may no longer exist. So don't forget to put in some error checking for that case. -- Walt ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
