Stems as associative memory (Was: Multi-dimensional arrays in REXX)
One sort of applying this technique of stems is to use the as associative memory - where the content of a storage location is used as an address. Ther rules for resolving elements of a stem variable state that all parts after the first part of a stem are subject to be resolved. As shown in ISDA (the small interactive disassembler in cbttape), which is completely written in Rexx, it works as folllows: Consider a hexcode sequence containing the following (hex)-characters: 0E1A this is resolved to: MVCL R1,R10 Internally it is accomplished by looking for the symbolic representation of x'0E' : OPCODE.0E.FORMAT = 'RR' ; OPCODE.0E.MNEMO = 'MVCL' the Rexx-instructions are: Inst_Form = getInstruction_Format(hexaopcod) . . . getInstruction_Format: arg hxo /* hexadecimal Opcode */ oform = opcode.hxo.fomat return oform /*returns 'RR'*/ . . .

SDSF problems in z/OS 1.9
Hi, We cut over to z/Os 1.9 last week and we’re have some problems: 1. Performance on the Output screen is slow. 2. The order in which multiple SYSOUTS from the same job are displayed on the output screen is wrong. We have jobs that create many sysouts. All of the sysouts have the same parameters (CHARS, FORMDEF, PAGEDEF, CLASS). The job has FREE=CLOSE coded. Once the job finishes and we look at the sysouts in the output screen we see that instead of the order being 1,2,3… it is 1,10,11,2,3…, Or in other words, the sysouts are sorted textually instead of numerically. 3. The order of the jobs on the Status screen is different than it was previously. For example, if I submit a job and it is assigned job number 65000, I wait a while, submit another job and it is assigned job number 100, then the first job (number 65000) will be displays below the second job (number 100). I would like the jobs to be displayed in the order that they were submitted. Our previous operating system was z/OS 1.7, where we had none of the problems. Has anyone seen these problems?

Re: Any Batch Pipes experience?

Is there a Web enabled TN3270 on z/10's running z/OS 1.9
Hi Cynthia, Under the web-enabled heading are a several solutions that provide TN3270 emulator, or emulator-like access to Z. IBM does not ship one with Z but has Host on Demand and HATS. Since you are going to replace a real emulator with a web-enabled one, opt for a product that downloads a client to the PC and runs it either inside the browser or as a separate window. There are a variety of ActiveX, Java, and Win32 web-enabled terminal emulators on the market that run directly from the Z/OS HTTP server. Some require the Web Sphere Application Server, while others will run from the Z/OS HTTP server, and do not require an application server. HTML emulators are not really suitable as a general emulator replacement, but are geared more toward casual use, anonymous use, or as the basis for GUI web enablement. Heads-down emulator users will find the HTML emulator too slow and that it operates differently from a real emulator. HTML emulators have their place, but not as an overall replacement for Aviva. Your Aviva users will probably expect a high level of functionality in any replacement you choose. Depending on the size of your organization, there may be some custom applications, macros, scripts, and other automation that have become part of daily operations. These will have to be migrated to the new solution to minimize the impact on the users. The migration also provides an opportunity to get these unmanaged or ad hoc processes under control and centrally managed. Good Luck.

This is a really nice example of the use stems can be put to once one stops thinking of them as arrays.

Re: SMP/E RECEIVE ORDER: Prerequisites?
The document you reference accurately describes features of IBMLink. IBMLink has a feature called SRD - Service Request and Delivery. 15-20+ years ago, back in the day when IBMLink was new, SRD was a major innovation - it allowed customers to support their environments and was the first (or second?) method available to customers to download PTFs from IBM electronically. During the subsequent decades, IBM has continued to add enhancements to SRD to add additional functions. Unrelated to IBMLink, IBM's Software Manufacturing and software order placement areas provided a new web based ordering mechanism called ShopzSeries. SMP/E RECEIVE ORDER interacts with IBM Software Manufacturing. RECEIVE ORDER has nothing to do with IBMLink. It became apparent to me that as soon as IBM provided ShopzSeries for ordering service (earlier this decade), and even more obviously because of the more recent addition of the RECEIVE ORDER function, both of which give all customers the ability to get every PTF available for their products, there was absolutely no reason for IBMLink SRD to even exist anymore. It's probably been more than five years since I last ordered a PTF using IBMLink. Ordering PTFs is NOT the justification for IBMLink's various pricing levels. The other features - premium response for ETR, search capabilities for problems, etc., ARE the justifications for IBMLink's various pricing levels. It's absolutely your company's decision how much each of those features are worth to your enterprise. My opinion, obviously.

The scheme is to unpack all the SMPPTFIN files to HFS; dynalloc all concatenated to SMPPTFIN and do the RECEIVE. In a test, I have even exceeded the OS limit on DD concatenations. A more economical approach would be to allocate SMPPTFIN to the output of a POSIX pipe and in a concurrent process unpack each SMPPTFIN archive, write it to the input of the pipe, and delete before unpacking the next. Yah, I know, this would create new error scenarios where an unpack failed midway in the process.

Re: SMP/E RECEIVE ORDER: Prerequisites?
Huge depends on what you have available for DASD at the time. If most of your volumes are allocated, and there is little room for anything new, 2 3390 Mod 3s to hold the HFS (now probably ZFS) could be huge. At my last contract job, we just got a new Shark when I started, and at that time there was triple the amount of DASD space. They decided to flash everything as a test, which gave me a GREAT test sysplex - all dasd was copied and totally separate from the production sysplex. Every time they asked me to allocate another 5 Mod 9s for something, there was plenty of room. Contrast that to my last full time job where in 1996 they still had lots of real 3380s and 3390s in their newly built datacenter. The dasd to hold double the amount of data just to hold an order wasn't available. Of course, neither was ShopZ back then, but a lot of smaller shops are still in that kind of situation. DASD is a lot cheaper now, but adding more still costs real money that many shops are unwilling to spend.

Re: COBOL and dynamic allocation (my two cents)
If I remember the OP correctly, s/he wanted to do some kind of table lookup to determine where to send output. We have an immense universal system to do this used on multiple plexes/lpars/... The core concept is to store the rules and related information somewhere and use that information to build the JCL. For us it is the distribution JCL. It could be just as well for a much smaller shop be to build the production JCL. In our case almost nothing is hardcoded except edit rules. (e.g. The class must be alphanumeric.) Tables built on main plex are sent to other plexes once a day. The only caution for an automated system like this is leave breadcrumbs everywhere. The constant complaint I didn't get my report can only be answered with hard data. I even have a way for a report program to very quickly use a subroutine to interrogate a file to see if there is a rule for the report. If not the report program does not run. At one item we had a billion lines a day backed up and going nowhere. IBM Mainframe Discussion List IBM-MAIN@bama.ua.edu wrote on 03/16/2009 10:22:01 PM: Yahoo is not putting the text of the original message for some reason. COBOL is a side issue (albeit small) in this case. Personally I find it abhorrent to hard code anything like destination in any programs. JCL is the ONLY way to go. It can be searched with multiple utilities (FILEAID and others) rather easily. This issue is that when (I did not say IF) a destination changes you must remember to recompile the program. If you do it in JCL then there is now recompilation and the change can be made with minimal impact. I had a programmer come to me a few years ago and he wanted to write a report that could go to multiple places. He wanted to do dynamic allocation (we were a strict COBOL shop). I do not have the memo I wrote him now or else I would paste in in here. To make things really simple just code a DDNAME and a DD and sysout=whatever, dest=newyork1 ddname2 DD sysout=whatever,dest=newyork2 etc etc and then in you COBOL program have an FD for each possible destination. The only rub to this is that there is a unknown (back then I came up with a number) max number of FD's IIRC it is around 1200. You may also want to code free=close on the DD statement. Yes it is a lot of JCL but a COBOL program that does dynamic allocation (even if its written in assembler or some other language) is a hard to maintain animal. Trying to change JCL in the middle of the night is easy compared to recompile and link edit and hey don't forget testing. If you set up the JCL correctly in the test phase it is a cake walk to production. I am not bad mouthing COBOL I am just say get realistic and look beyond coding and testing. It will make life a lot easier. Plus if you want you can dd dummy out the DDNAMES in testing and when the JCL goes to QA it will be easy, IMO.
