i had hacked hasp on mvt 15/16 to implement syntax of the cms editor (from scratch) and crje function ... that i thot was better than tso (when it came along) ... with both 2741 and ascii/tty terminal support. I had earlier done the ascii/tty terminal support for cp67. Part of doing ascii/tty terminal support ... i tried to make the 2702 controller do something that it couldn't quite do ... which was part of motivation for clone controller effort at the univ (four of us got blamed for clone controller business in writeup). much later the company declared cms as the "strategic online/conversational solution" ... which appeared to prompt the TSO product manager to ask me if i would be interested in redoing mvs scheduler (in attempt to improve TSO human factors characteristics). old email reference ... http://www.garlic.com/~lynn/2006b.html#email80310 part of this had shown up with the introduction of 3274 controller ... the channel attached 3274 controller (for 3278) had significant higher processing latency than the channel attach 3272 controller (for 3277) resulting in increase in response; however tso base response was already so bad ... it didn't notice the difference. some numbers from old comparison in this post http://www.garlic.com/~lynn/2001m.html#19 3270 protocol one of the issues was that several operations had difficulty adapting to the 23jun69 unbundling announcement and starting to charge for software ... including requirement that revenue had to be at least as much as cost/expenses. there was a little latitude being able to make the calculations at the organization level (aggregate revenue from multiple products against aggregate costs). old posts about ISPF being able to match up with another product to offset its high run rate (not being able to actually charge enuf for ISPF to offset the costs). misc. past posts on the subject http://www.garlic.com/~lynn/2000d.html#17 Where's all the VMers? http://www.garlic.com/~lynn/2001m.html#33 XEDIT on MVS http://www.garlic.com/~lynn/2009s.html#46 DEC-10 SOS Editor Intra-Line Editing http://www.garlic.com/~lynn/2010g.html#6 Call for XEDIT freaks, submit ISPF requirements http://www.garlic.com/~lynn/2010g.html#50 Call for XEDIT freaks, submit ISPF requirements http://www.garlic.com/~lynn/2010m.html#84 Set numbers off permanently -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
