Can anyone please share a CICS (COBOL) wrapper program example for a zOS connect.
I am have to use DEPENDING CLAUSE for the same. So far I am new to zOS thing.
I have to use channels and containers.
Example if any please.
Are you sure you need a wrapper program? The tooling for z/OS Connect supports Occurs Depending On as long as the object (the field containing the number of occurrances) is in the same structure as the variably occurring field.
For example, z/OS Connect supports this:
01 My-structure.
03 Some-data pic x(13).
03 Data-count pic s9(4) comp.
03 Lots-of-data pic x(20)
occurs 1 to 6 times
depending on Data-count.
But if "Data-count" is not defined within "My-structure", it is not supported.
See my next answer on a technique to handle occurs depending on if your copybooks are not structured the way that z/OS Connect supports.

I'm developing an OBD-II reader where I want to query requests to read PID parameters with a stm32 processor. I already understand what should go on the data field, but the ID is giving me a headache. As I have read, one must send 0x7DF to broadcast a request, and each ECU will respond with his own ID. However, I have been asked to do this within the SAE J1939 protocol, which uses the 29 bit extended identifier, and I don't know what I need to add to this ID.
As I stated in the title, could someone show me some actual data from a bus using this method? I've been searching on the internet for real frames but did not have any luck so far.
I woud also appreciate if someone could shred some light to if the OBD-II communication needs some acknowledgment to work properly.
Thanks
I would suggest you to take a look on the SAE J1939 documentation, in the more specifically on the J1939/21,J1939-71 and J1939/73.
Generally, a J1939 transport protocol response sequence can be processed as follows:
Identify the BAM frame, indicating a new sequence being initiated
(via the PGN 60416 - 0xEC00 can be reach by 0x1CECFF00 )
Extract the J1939 PGN from bytes 6-8 of the BAM payload to use as the
identifier of the new frame
Construct the new data payload by concatenating bytes 2-8 of the data
transfer frames (i.e. excl. the 1st byte)
A J1939 data transfer messages with ID 1CEBFF00 (PGN 60160 or EB00).
Above, the last 3 bytes of the BAM equal E3FE00. When reordered, these equal the PGN FEE3 aka Engine Configuration 1 (EC1). Further, the payload is found by combining the the first 39 bytes across the 6 data transfer packets/fram
The administrative control device or any device issuing the vehicle use status PID should be sensitive to the run switch status (SPN 3046 - 0xFDC0 which probably can be reach by 0xCFDC000) and any other locally defined criteria for authorized use (i.e., driver log-ons) before the vehicle use status PID is used to generate an unauthorized use alarm.
Also, you can't forget to uses a read/send to extend ID message, since that is a 24-bit.
In fact, i will suggest you to use can-utils to make your a analyses even easier. A simple can-dump or can-sniffer you can see what is coming on your broadcast.

I'm completely new to tcl and am trying to understand how to script the command "adapter usb location" in openOCD.
From the openOCD manual, the command has this description:
I want to point it to the port with the red arrow below:
Thanks.
It's not 100% clear, but I would expect (from that snippet of documentation) a bus location to be a dotted “path” something like:
1-6
where the values are:
1 — Bus ID
6 — Port ID
Which would result in a call to the command being done like this:
adapter usb location 1-6
When there's a more complex structure involved (internally because of chained hubs) such as with the item above the one you pointed at, I'd instead expect:
1-5.3
Notice that there are is a sequence of port IDs (5.3) in there to represent the structure. The resulting call would then be:
adapter usb location 1-5.3
Now for the caveats!
I can't tell what the actual format of those IDs is. They might just be numbers, or they might have some textual prefix (e.g., bus1-port6). Those text prefixes, if present, might contain a space (or other metacharacter) which will be deeply annoying to use if true. You should be able to run adapter usb location without any other arguments to see what the current location is; be aware though that it might return the empty string (or give an error) if there is no current location. I welcome feedback on this, as that information appears to be not present in any online documentation I can find (and I don't have things installed so I can't just check).
I also have no idea what (if anything) to do with the device and interface IDs.
I am trying to build a neuronal network with CNTK to estimate the age of a person.
Currently I want to try an approach using only one class. So every picture gets label 0 but also an affiliation to the class in percent.
So the net should learn that the probability of a 30 year old person to match class 0 is 30% ... 60yo = 60% ... 93yo = 93%.
Currently I am working on a reduced data set of 50k images (.jpg) and use the MiniBatchSourceFromData function.
Since I have a lot more training data available (400k + augmentations) I wanted to load the pictures in chunks for training, due to limited server RAM.
Following THIS CNTK tutorial I have to use the MiniBatchSource function and feed a deserializer with a map_file which includes the paths and labels to my training data. .
My Problem is, that the map_file doesn't support class affiliations. I can only define what picture belongs to which class.
Since I am new to CNTK and deep learning in general, I'd like to know if there is another option to read chunked data as well as tell the network how likely it is that the picture corresponds to a specific class.
Best regards.
You can create a composite reader. One deserializes you images, another can deserialise your numeric data.
Read this, the last section shows you how to use a composite reader
So I'm doing some hobby-related stuff which involves taking Fourier transforms of large real arrays which barely fit in memory, and was curious to see if there was an in-place version of rfft and irfft that saved RAM, since RAM consumption is important to me. These transforms are possible despite the input-vs-output-type mismatch, and require an extra row of padding.
In Implement in-place rfft! and irfft!, Tim Holy said he was working on an in-place rfft! and irfft! that made use of a buffer-containing RCpair object, but then Steven Johnson said that he was implementing something equivalent using A_mul_B!(y, plan, x), which he elaborated on here.
Things get a little weird from then on. In the documentation for both 0.3.0 and 0.4.0 there is no mention of A_mul_B!, although A_mul_B is listed. But when I try entering them into Julia, I get
A_mul_B!
A_mul_B! (generic function with 28 methods)
A_mul_B
ERROR: A_mul_B not defined
which suggests that the situation is actually the opposite of what the documentation currently describes.
So since A_mul_B! seems to exist, but isn't documented anywhere, I tried to guess how to test it in-place as follows:
A = rand(Float32, 10, 10);
p = plan_rfft(A);
A_mul_B!(A,p,A)
which resulted in
ERROR: `A_mul_B!` has no method matching A_mul_B!(::Array{Float32,2}, ::Function, ::Array{Float32,2})
So...
Are in-place real FFTs still a work in progress? Or am I using A_mul_B! wrong?
Is there a mismatch between the 0.3.0 documentation and 0.3.0's function library?
That pull request from Steven Johnson is listed as open, not merged; that means the work hasn't been finished yet. The one from me is closed, but if you want the code you can grab it by clicking on the commits.
The docs indeed omit mention of A_mul_B!. A_mul_B is equivalent to A*B, and so isn't exported independently now. A_mul_B! would be used like this: instead of C = A*B, you could say A_mul_B!(C, A, B).
Can you please edit the docs to fix these issues? (You can edit files here in your webbrowser.)
I have a small problem while trying to do ocr using the tool gocr. It sometimes recognizes an o as zero and vice versa. To solve this, i tried to make it use a user specified database path. But doing that would require me to create a map for all possible characters. Is there any way in which i could tell gocr to just use the manual db for only these 2 characters??
Thanks
I'd suggest you just put those two characters in the db.lst file, and use it along with the ocr-engine...
so long
