Everybody would like to get rid of assembler, especially in application programs and exits. There was a lot of work in the 90s and naughties decommissioning those exits which still isn’t complete. For vendors and subsystems like IMS it’s so pervasive you can’t get rid of it. Even with PL/X becoming popular all of the interrupt handlers are still written in assembler. Same for the syscall SVC in zLinux. > Regards, > David > > On 2023-09-12 08:56, Bill Johnson wrote: >> Making up scenarios that never or almost never happen. >> >> >> Sent from Yahoo Mail for iPhone >> >> >> On Tuesday, September 12, 2023, 8:53 AM, David Spiegel >> <00000468385049d1-dmarc-requ...@listserv.ua.edu> wrote: >> >> Hi Jon, >> Now that you've mentioned DB2, please tell me how to write/maintain a >> DB2 Secondary Authorization Exit WITHOUT Assembler. >> Next time my customer asks me to amend it, I will be sure to give them >> your answer.
