IBM may do things internally, even in customer-facing code that
are not documented; non-GUPI.  Many years ago, I complained
here that
//NAME  IF FALSE THEN
seems to work as expected, but is documented as "unpredictable".
Why doesn't IBM:
o make it predictable
o document it as it predictable operates
o or prohibit it by making it a JCL error.

"Unpredictable" is treacherous.

Peter Relson (IIRC) riposted that many such constructs are either
reserved for IBM internal use or for future development which may
contradict our empirical inferences about their implementation.

[ lots of them. ]  IBM is free to rescind their unsupported operation and
correspondingly modify those installation  scripts.  Would Peter disagree?

But since $( ... ) is unquoted, shell tokenizes it as awk needs:
598 $ echo $( cat dsns )
"//'SYS1.MACLIB(ACB)'" "//'SYS1.MACLIB(CHECK)'" "//'SYS1.MACLIB(CLOSE)'" 
"//'SYS1.MACLIB(DYNALLOC)'"

almost like:
601 $ cat dsns | xargs echo
//'SYS1.MACLIB(ACB)' //'SYS1.MACLIB(CHECK)' //'SYS1.MACLIB(CLOSE)' 
//'SYS1.MACLIB(DYNALLOC)'   

versus:
599 $ echo "$( cat dsns )"
"//'SYS1.MACLIB(ACB)'"
"//'SYS1.MACLIB(CHECK)'"
"//'SYS1.MACLIB(CLOSE)'"
"//'SYS1.MACLIB(DYNALLOC)'"

But don't the quotation marks confuse fopen() in awk?  Or does
fromdsn magically strip those?  Ah!  I see xargs strips them!

OK.  COZBATCH runs ini the job step address space.  And it
can spawn() sh locally into that same address space.  But
doesn't sh need to fork() fromdsn to run the pipe, thereby
losing the "//DSNS DD   *"?

Does it tokenize differently from sh?  Yes, but not here.

Re: [MVS-OE] Running z/OS Unix commands from an MVS sequential dataset

$(fromdsn //DD:DSNS)  
returns a multiline string as one arg.   Actually it won't work, since $(  ) 
does a fork into a different address space and the DD isn't there.

xargs is completely different, but works perfectly for when you want to 
tokenize a stream into additional arguments for a command.

In utter ignorance of "fromdsn", I wonder. What can xargs do that
can't be done equally we'll with command substitution, e.g.:
//STDIN DD  *
   awk '/STR/ {print FILENAME ":" NR "\t" $0 }' $(

I've found xargs useful only with non-portable filenames, then:
find ... -print0 | xargs -0 

Alas, z/OS supports neither "find ... -print0" nor "xargs -0"

Thanks again Kirk - I too love those goofy shell quotes ().

Could also conceivably use a "here document" for the inputs to the first awk

showing off .

xargs takes a command template and runs it with all of the words read from 
stdin tacked on as args.   This works well with awk since it takes a list of 
filenames to process as arguments.

FWIW, you can also use awk to read a list of dsns (without "//'...'" ).  This 
also shows that since awk uses fopen that it can read from DDs if it's run in 
the same address space as the shell.   For Gil :-)

//AWK  EXEC PGM=COZBATCH
//DSNS DD   *
SYS1.MACLIB(ACB)
SYS1.MACLIB(CHECK)
SYS1.MACLIB(CLOSE)
SYS1.MACLIB(DYNALLOC)
/*
//STDIN DD  *
awk '{print "\"//'\''" $1 "'\''\"" }' //DD:DSNS |
  xargs awk '/STR/ {print FILENAME ":" NR "\t" $0 }'
//

But I mostly like it because of the goofy shell quoting that it required :-)

This is how I would do it.

- You can make awk not only act like (f)grep, but it also takes dsn syntax  
since uses fopen()
- awk will also read multiple files in one execution, so this will run rings 
around other ways that require a couple of forks for every dsn that you are 
searching.
- you can also customize how the output looks (see below)

//AWK  EXEC PGM=COZBATCH
//DSNS DD   *
"//'SYS1.MACLIB(ACB)'"
"//'SYS1.MACLIB(CHECK)'"
"//'SYS1.MACLIB(CLOSE)'"
"//'SYS1.MACLIB(DYNALLOC)'"
/*
//STDIN DD  *
fromdsn //DD:DSNS |
  xargs awk '/STR/ {print FILENAME ":" NR "\t" $0 }'
//

Replace STR above with your regex.
You can make this work with BPXBATCH and cat instead of fromdsn, but its not 
nearly as slick :-)

Re: non Db2 DFSort and zIIP question [EXTERNAL]

[Attila Fogarasi]

SMF16 records for DFSORT show how much cpu time was zIIP eligible and how
much was actually dispatched on zIIP.  You can check your own system to see
what relevance it has for your workload.  In the past only Db2 Utilities
workload was zIIP eligible in DFSORT, but that may have changed recently (I
don't know if IBM finally did it).  Lots of other non-Db2 zIIP exploitation
is out there.

No.  That fails for human error, indolence, and bias ("We don't need
no steenkin UNIX -- we got along fine without it in 1968!")  That
provoked the OP's perplexity.

Rather, there should be a single point of control in PARMLIB, perhaps
HMC, in which a value could be entered in the format described in
UNIX System Services Command Reference, Appendix I. TZ environment
variable.  This implies the current offset and schedule of Daylight
Saving changes.  Control block entries such as CVTLDTO can be
derived from this, preferably automatically.  Existing control block
entries do not provide sufficient information to calculate the TZ
environment variable such as for:
Australia/Canberra: "AEST-10AEDT,M10.1.0,M4.1.0/3"
America/Denver: "MST7MDT,M3.2.0,M11.1.0"

That system setting should govern the behavior of processes ini
which TZ is unset, rather than the current default of UTC.

Re: non Db2 DFSort and zIIP question [EXTERNAL]

[Pommier, Rex]

Thanks, Paul.  That definitely answers my second question.  I haven't seen the 
Redbook so this clears up whether ZSort uses a zIIP.  Kind of makes me wonder 
if SyncSort's (OK, "Precisely's") ZPSaver would take advantage of the new 
instructions.  Best of both worlds on a significantly sub-capacity machine.  
Use new instructions that accelerate sorting on a full speed zIIP.  :-)

Back to my original question since I don't have a z15, does DFSort exploit zIIP 
at all?  I'm guessing "no" since I've seen nothing current about it.

Thanks again,

Rex

Hello list,

The subject line summarizes my question.  We're running a z14 (so the SORTL 
stuff doesn't apply according to the doc I've read) and z/OS 2.4.  Does DFSort 
support offloading to a zIIP processor for non Db2 sorting?  I know I could 
purchase db2sort which is Syncsort under the covers for db2 sorts but I'm 
wondering about regular batch EXEC PGM=SORT usage of DFSort.  I found a hit 
from about 8 years ago where at that point they didn't exploit a zIIP but was 
wondering if anything has changed.

On a second subject, if we ever migrate beyond the z14, is the SORTL stuff 
available on the z15 and above (presumably) using zIIP or is it merely doing 
other acceleration on the general purpose engines?

TIA,

The drawbacks are:

  Suppose IBM, to benefit one customer changes, e.g. an
  autoconversion behavior that impacts another.

As an ISV, do you rely on unsupported behavior in customer-facing

Gil, 
We certainly have seen that using data sets from z/OS Unix commands that don't 
explicitly document support is your pet peeve.   IMO this seems overly 
pedantic, since IBM code that uses fopen (and works) is extremely unlikely to 
stop.

and setting the TZ values in CEEPRM00, that parm + the profile settings 
in etc use the same TZ values to keep the time zone in sync during time

the STP External timer keeps the CPC clock in sync

Hello

Good morning

I see OMVS and MVS have their own time and date settings.

Isn't their a way to have a common configuration settings for  date and
time for MVS and OMVS ?

fgrep doesn't use a regex; awk match() requires a regex.

in a regex?

Is ISRSUPC SRCHFOR an alternative?

[Lennie Dymoke-Bradshaw]

Mike,

I am interested in running Vista 3270 in my Ubuntu system. 
Are there any instructions for what I need to do to get this working?
I have no experience with Wine.
