In the Auth Assembler guide, it is stated that IRBs (created by CIRB) get control with an empty DU-AL :
“Upon entry, the exit routine runs with an empty dispatchable unit access list (DU-AL). To establish addressability to a data space created by the mainline routine, the exit routine can use the ALESERV macro with the ADD parameter, and specify the STOKEN of the data space.” Rob Scott Rocket Software From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Seymour J Metz Sent: 12 October 2020 09:14 To: [email protected] Subject: Re: ALERSERV delete from stimerm exit EXTERNAL EMAIL I was relying on what Peter Relson wrote, but I checked the extended addressability guide and it shows a DU-AL only for SRB and TCB, not for individual RBs. Peter, if you see this, please clarify. -- Shmuel (Seymour J.)
