How is a PDSE represented in the ECB? I understand that the hazard in extending a shared PDS is that an added member may have a TTR identifying an extent not in a sharing job's ECB. Does PDSE eliminate this hazard by appearing as a single extent? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
