Hi Tom,
That is one of the arguments for non-OCO. Customers would have the
ability to suggest code improvement/fixes, much like Open Source today
(which IBM schizophrenically) supports.
Another IBM mistake was to not make PL/X (or PL/AS) publicly available.
While I am mentioning IBM mistakes, the biggest ongoing mistake is to
not allow z/OS to be run on any hardware other than which was licensed.
Yes, I am familiar with the "our lawyers will not permit this" argument
-- poppycock! The industry is screaming for fresh blood, yet, the golden
goose is being starved. SMH.
Regards,
David

I had worked on PC's and Computervision graphic machines prior to
1983, and everything there was already OCO I think, so I didn't know
any better when IBM went OCO. I rarely looked at the fiche, but it
was really interesting to see PL/X (I think it was called) compiled
into assembler code. I do remember one time where (with someone
else's help) we found the cause of an error by looking at the fiche
and reported it to IBM - with our own fix of course :)

Hi Tom,
1983, eh?
The same year as the (expletive deleted) OCO policy.
I've seen IBM-lifers defend it on this forum, yet, it still did
not/does not make sense.

I get it... I just heard from an old co-worker that sometime this
month they shut down the mainframe in Southern California that I
worked on from 1983 to 2013. That was my first exposure to an IBM
mainframe, and I think XA had just come out and people were busy
fixing programs to work in AMODE 31. There was a rack full of MVS
microfiche and a viewer at each desk. If we needed to send a dump
to IBM we had to create a tape and carry it across the street to the
mail room.

When I came to school in 1976, the computer was described as
"loosely coupled 370s". My exposure was via remote cardreader/printer.
When I started working here in 1981, there were still folks that
had rewired boards for what they had before that.
End of 2019, we moved from a 10 year old z9 to MFaaS with FNTS in
Omaha.
