I second that! Bob Rogers (no longer at IBM...) ran a series of "How Do You Do What You Do When You're a (z10/z196/z13) CPU?" sessions over the years. But they were more focused on overall characteristics of the system, not on specifically how an assembly language programmer can best exploit the hardware. A session that presumes that background knowledge and really gets down into the weeds would be great. And maybe follow it up with a BOF for assembly weenies to address specific questions. How about it, IBM? Surely there must be someone Poughkeepsie who wants to visit San Antonio in March? :-) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
