You'll find a bit more discussion about it on the VM listserv. While z/OS is a
requirement for the care and feeding of z/TPF, we use VM extensively as a
development and test platform. And yes, a hotel is an airplane without wings.
We used TPF for rates and inventory at Holiday Inn/BHR/IHG
Maybe you've asked the IBM RFE site to send you an email when someone posts an
RFE, I have done so for PL/I, TSO, HLASM, ISPF, and SDSF, and at the last few
weeks I've been bombarded (in the nice sense) with emails like
RFE created ID:149399 ISPF Edit highlighting for ACS routines

I worked at an airline in the 90s. I was on the OS/390 team.There was an
equivalent(much larger) TPF team. it is a very unique operating system. All
it could do (and did it very well) was handle high volumes of transactions
and database calls. I expect it has not changed much. Everything else,
Also , there is a z/OS based product - ALCS - which provides the same
functionality as TPF without the overhead of additional hardware, operating
system , operational costs etc . So targeted at smaller shops.

Others have already covered some of the points and there is more about the
history of z/TPF here - (I won't repeat what's already mentioned Wikipedia):

Well,
I thought there are important differences:
- hotels usually have more "seats".
- hotel have no time schedule for departures and arrivals. You cannot
book a seat 5 minutes after departure, while in hotel it is possible all
the time. IMHO this is the most important difference.
- of course
I tried something similar in PL/1, many years ago. If I remember right, I
had to have two pointers, one based(addr(other_pointer)). All this to
achieve R1 -> ptr -> list of TUPs for SVC 99. One of them was a pointer to
a function.
It looked dirty to me, but...
I showed the guy running the team,
Programs on ACP were limited to 4k size originally, and files were limited
to 2 record sizes (short and long), the sizes being optimized for 3211 disk
geometry. Those limitations were removed 40 years ago :) However the
speed of zTPF comes from not allowing applications to do things that
require

Most likely reason is that the READ isn't complete yet. Possibly

Normally a CHECK just waits on the ECB and does a minimal amount of
processing.

Peter,
I don't know if this could be the base of what you need, however I'd like to
point you to a github page for something that Walmart did for generating unique
zUID, guaranteed to be unique until the year 34,000 (built with patent pending
algorithm). It was built as a cloud solution,
-- It appears that the "uniqueness" applied by the programmable field is
limited to the sysplex. It has nothing to do with an LPAR (aside from that
z/OS runs within one). There is no uniqueness across sysplexes.
-- It appears that the current implementation uses the "system number"
managed by
PoOps "Figure 4-12. Format of the TOD Clock, ..." shows that SCK does
not affect the Epoch Index. "Additionally, the PTFF instruction [*may*]
manipulate the TOD clock and epoch index, ..." "may" or perhaps not?
I tired of searching before I found particulars of PTFF.
Is it anticipated that
STCKE is I believe guaranteed unique by architecture. Db2 would fall on its
face without that.

Understood, but I know no guarantee that any proper substring of
the STCKE value is unique.

Is there a CMS command which will search a minidisk (or group of minidisks)
for files containing a specific string?
Don't see anything obvious in the CMS manual.

Ask on IBMVM and CMS-PIPELINES.
I've used SRCHFOR from the rare and
There is not a 'standard' search tool in VM. There are numinous versions
that are available for the asking. Just post a request on the VM list.
Almost all of them are just a rexx wrapper for the xedit locate function.
I have attached one of my may versions, the one I use mostly.

My wild guess is that Tom Brennan knows a TN3270 client when he sees one.
