It's best to use whichever is fitted to the task at hand. There is no one size fits all.

But nowadays it no longer is. I am unsure what changed but I think there was a change somewhere, possibly in the cross-memory instructions.

For what it's worth, you don't need to go through all the rigamarole of an SRB to go poking around in another address space. Given the proper authorization, you can: - Issue an AXSET, specifying a value of 1 - Issue an SSAR instruction identifying the target address space as the secondary address space - Use MVCP / MVCS instructions to copy data between your primary address space and the secondary address space There is also the technique of using the special ALET value of x'00000001' and using AR mode to reference data from another address space. =============================== Adam Johanson Broadcom Mainframe Software Division ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] <mailto:[email protected]> with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] <mailto:[email protected]> with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] <mailto:[email protected]> with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
