Re: Any idea how a batch pgm (fetchable routine) can find out by which program it was fetched?
I think the JSCBPGMN field of the JSCB is what you're looking for - it holds the job step program name.

Another way is to look at the SWA for the executing step. This is not done with chain chasing and will always give you the actual initial program.

Re: C++ fstream, iostream and z/OS
There's no doubt that z/OS specific functions aren't documented that well, but the Run-Time Library Reference is where it all is. Functions are for both C and C++. It includes some z/OS specific functions like __cabend (abend a process) and _malloc24 (getmain storage below the line), but you have to really look for them. As you've found, fopen() works for z/OS datasets, specifying a DD using the //DD:ddname format, or a sequential filename using the //'dataset.name' format. Works for VSAM too. There are also the VSAM specific flocate() and fupdate() functions. Unfortunately, I haven't found anything like FIND for searching through PDSs.

Re: Does SAC 0 make PASN = HASN = SASN
Thanks Rob, Chris and Binyamin for your comments. I've learnt a lot from them. A couple of questions for the panel: Chris, you said that: Using AX=1 and SSAR to another address space is not very clearly documented by IBM because it is a violation of the MVS xmemory architecture. This comes as a surprise, as I've seen this used in many different programs. Setting AX=1 will certainly allow you to access any address space's memory, but unless you have another TCB needing to AXSET to something other than 1, I can't see how this may not work, or could cause difficulties. Can you give more details? You also said that using ASC mode doesn't remove the need for the target address space to be swapped in. Short of a paging error, what could go wrong here? Binyamin, you've suggested grabbing the LOCAL lock when the SSAR succeeds. Why do you suggest this? Thanks again for your comments.

Re: DLL Recomendations?
Hi Art, I didn't find any noticeable performance degradation using DLLs vs static binding. However I haven't done any serious testing. Some other thoughts off the top of my head: - DLLs have to be re-entrant - no problem with C modules, but your Assembler modules may need some tweaking. - XPLINK and non-XPLINK really don't mix. So if one module is called by both, you'll either need two flavours (XPLINK and non-XPLINK), or write an Assembler 'glue' routine that somehow gets around the problem. Two flavours is much easier. - If you're writing an Assembler module DLL to be called by an XPLINK module, you'll need to use the EDCXPRLG and EDCXEPLG macros in place of the normal LE CEEENTRY and CEETERM macros. - If you have a C module with functions (no mainline code), I found that you still need a main() statement to create a CEEENTRY entry point for your module. Without this, LE won't play with your module. - It took me some time to figure out side files, and that you need to include them when binding the modules that will call your DLLs. - It sounds like you've only got C programs calling DLLs, which is fine. If you have COBOL or PL/1 programs, it's a lot harder. If you haven't found it already, the article at http://www.ibm.com/developerworks/aix/library/au-bordercrossing/?S_TACT=105AGY06; talks a lot about DLLs and XPLINK, and has other handy links. David Art Celestini wrote: We have a variety of CSECTs that are statically bound into several different load modules. These are mainly IBM C programs with a smattering of Assembler. We are considering moving these into a set of DLLs to reduce redundancy and simplify maintenance. I am interested in any guidance list contributors might be willing to offer in terms of dos and don’ts, gotchas, etc. regarding DLLs, especially as it may apply to performance. One consideration is that many of these modules are used in both batch and CICS, and in both XP- Link and non-XP-Link environments. We are not opposed to the notion of creating multiple DLLs for these different environments, if necessary.

Re: Java on z/OS JNI Sample Wanted - Preferably HLASM
Have a look at the (very rough) draft article at http://www.longpelaexpertise.com.au/ezine/HLASMfromJava This shows how to call an HLASM module from Java, with code examples. However this uses C for the JNI code. Martin Packer wrote: Could someone point me to a good simple sample of a HLASM JNI method being called from Java on z/OS? Failing a HLASM one I'd accept some other language. Pointer to a basic doc also appreciated. (Project involves also getting Jython to call a JNI method.)
