Re: Learning Rexx (was: Need tutorial)
Gee, I don't want to pose as an expert in the relative benefits of various Rexx environments. I have near-zero experience on 'nix and USS, no recent (15 years) experience on CMS, and although I have written large systems in Rexx, I am not at present writing much Rexx beyond basic TSO helper scripts. I certainly don't want to contribute to an OS war. I was just answering the question about how to learn Rexx, and if you happen to have access to both, IMHO CMS is a more Rexx-friendly place than TSO. It's really a separate topic, but I think there is little doubt that it makes sense to edit code of any sort in some fast character-at-a-time interactive environment even if the target compile and/or execution environment is z/OS. My particular choice is MS Visual Studio, but I only claim that it makes sense for me, not that it is the best for everyone.

Before USS was available I tended to edit JCL on CMS with XEDIT; nowadays on Solaris, often accessing legacy data sets with NFS. NFS will deal with PDSE; I suspect that CMS would have trouble ACCESSing a PDSE, and writing to any legacy z/OS data set from CMS is questionable, as is catalog search. I use TSO/ISPF, now as earlier, largely for: o SDSF o DSLIST o DDLIST o Testing with a customer-like environment. I keep one ISPF session active, and as many USS or Solaris as convenient; I've never mastered WSA.

Re: Need tutorial
Nobody has mentioned much about COBOL. Depending on what the OP wants to learn, and his home system. He might be interested in GNU COBOL (formerly OpenCOBOL) at http://www.opencobol.org . Or, perhaps even more so, zCOBOL, at http://www.z390.org/zcobol/ . zCOBOL runs on Linux and Windows. It is very similar to z/OS Enterprise COBOL, a good way to learn COBOL on the cheap (only costs $0.00!). But Wait! There's More! It also comes with a CICS emulator as well. Now what would you expect to pay?!? It's still the low, low cost of $0.00! What's the catch? It's written in Java. So you do need to have Java installed on your desktop. However, I personally rather like Java.

Re: Spawned Address Space Control in tcsh shell
This is my take on it. I am not an expert. Nor do I have access to the actual source code. I don't believe that tcsh will do what you want. My reasoning is below. In order to run a process in the same address space, the code must use the spawn() function. I base this assertion on http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/BPXZB1C0/2.209 , point #8 in the Usage Notes. This talks about the _BPX_SHAREAS environment variable. This environment variable is not mentioned anywhere in the documentation of tcsh. I note that the description of the fork() function does not mention _BPX_SHAREAS at all. I therefore conclude that a fork() will always result in a new address space. I note that the description of the execve() function says: The current process image is replaced with a new process image for the executable file to be run. That is, the old execution state ceases to exist. So if the tcsh did an execve() without the fork() in order to run in the same address space, the shell would exit after the command because the shell would have ceased to exist. In my mind, doing a exec() is much like doing an XCTL. You don't return from whence you came. I notice that on this page: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/BPXZA5C0/TCSHBUINONit states: When a command to be executed is found not to be a built-in command the tcsh shell attempts to execute the command via execve. Taking these things together, I have come to the conclusion that the tcsh shell _most likely_ invokes non-builtin commands in the original UNIX way. That is doing a fork() followed by an exec(). This removes the possibility of running cozsftp in the same physical address space as the shell. Any particular reason you wan to use tcsh? I'm just curious because I've never read anything nice about it.

Major, Minor CDE
Hi, I have been chaining the CDE entries looking for the executing program of the job step. I started from ASXBFTCB looking at TCBJPQ which had a CDE entry but not for program on the job step. At the third TCB using TCBTCB as a forward chain. Looking at TCBJPQ the 2nd forward chain CDCHAIN I found the program. Is there any way of knowing what cdentry represents the program job step Mind you I did this under TSO TEST So I did bump in to some TEST CDE entries.

Re: VB FTP z/OS to z/OS (again?!)
Since EBCDIC is a specific encoding for text glyphs, I would have to agree with Frank that specifying EBCDIC certainly should imply one is discussing text data. I have no idea if documentation on z/OS FTP explicitly states that or not; but if its usage there is not intended to imply text data, then this parameter value is mis-named. Joel C.

Re: Spawned Address Space Control in tcsh shell
John , This talks about the _BPX_SHAREAS environment variable. This environment variable is not mentioned anywhere in the documentation of tcsh. Your are right . BPX_SHAREAS cannot be used for tcsh . It is documented in USS planning guide . _BPX_SHAREAS Specifies whether the spawned child process is to be run in a separate address space from the login shell's address space or in the same address space. Use _BPX_SHAREAS is to improve performance in the z/OS® shell. The spawn callable service uses _BPX_SHAREAS when creating child processes. Restriction: If tcsh is your login shell, do not use BPX_SHAREAS. YES The child process is created on a subtask in the parent's address space. If the request cannot be honored, the child is created in another address space. NO The child process is created in a new address space. NO is the default. MUST The child process is created on a subtask in the parent's address space. If the request cannot be honored, the request will not complete. On Monday, December 30, 2013 7:23 PM, John McKown john.archie.mck...@gmail.com wrote: This is my take on it. I am not an expert. Nor do I have access to the actual source code. I don't believe that tcsh will do what you want. My reasoning is below. In order to run a process in the same address space, the code must use the spawn() function. I base this assertion on http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/BPXZB1C0/2.209 , point #8 in the Usage Notes. This talks about the _BPX_SHAREAS environment variable. This environment variable is not mentioned anywhere in the documentation of tcsh. I note that the description of the fork() function does not mention _BPX_SHAREAS at all. I therefore conclude that a fork() will always result in a new address space. I note that the description of the execve() function says: The current process image is replaced with a new process image for the executable file to be run. That is, the old execution state ceases to exist. So if the tcsh did an execve() without the fork() in order to run in the same address space, the shell would exit after the command because the shell would have ceased to exist. In my mind, doing a exec() is much like doing an XCTL. You don't return from whence you came. I notice that on this page: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/BPXZA5C0/TCSHBUINONit states: When a command to be executed is found not to be a built-in command the tcsh shell attempts to execute the command via execve. Taking these things together, I have come to the conclusion that the tcsh shell _most likely_ invokes non-builtin commands in the original UNIX way. That is doing a fork() followed by an exec(). This removes the possibility of running cozsftp in the same physical address space as the shell. Any particular reason you wan to use tcsh? I'm just curious because I've never read anything nice about it.

That's analogous to claiming that Rexx is superior on z/OS because of address SYSCALL (others might say ISPEXEC/ISREDIT). Perhaps. But pipes are part of the base CMS product and are considered fundamental to REXX programming on VM. On z/OS they are either a very expensive add-on product or have to run in the POSIX subsystem. Designing routines to co-operate in a pipeline is a very different programming paradigm to what the vast majority of REXX programmers on z/OS are familar with. NetView had pipes and they were incredibly useful for processing message streams. I used to miss that functionality when coding TSO REXX. Of course, IBM are in the business of making a buck; but it's a travesty that they never made pipes, both TSO and batch, part of the base software stack. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
