Re: F against a REXX STC
Can I send MVS modify command against a REXX that is running as an STC? I did something very similar with a Cobol program. I guess that you can do the same in Rexx (set-up of the environment may be a little harder, though). I've written an assembler program that set's up the plumbing for handling the start, modify and stop MVS commands and then attaches a subtask that is running the Cobol program. Communication between the assembler and the Cobol program, in my case, is a simple structure in the assembler programs' working storage, mapped in the Cobol LINKAGE SECTION. When a modify command comes in, the assembler code handles it, analyzes the meaning of it and puts the corresponding values in the communication structure. It then POSTs an ECB on which the Cobol program (through a call to an other little assembler sub-routine) is waiting. Cobol program picks up the parameters from its linkage and processes. In the main assembler program I have also a STIMER that pops every-so-often and writes out a WTO to say it is still alive. This prevents the process from abending for inactivity time-out when it is running as a simple job (handy during testing...)

Re: F against a REXX STC
More specifically, google for QEDIT +assembler +MVS and look at the WAITREXX page from Xephon. Just googling QEDIT gets you to the semware.com page for the PC file editor QEDIT, now named The Semware Editor, a fine tool indeed (disclaimer: I have owned/used/recommended it since PCDOS days) but not what you would be looking for here.

I just want to trigger a specific function using this modify command on a loop-wait REXX STC. How this is implementing? Well, the only thing that comes to my mind is to run an HLASM program within your REXX code which would test the CIB chain (QEDIT macro) and, if one exists, process the first MODIFY command and return the parameters from it in REXX variables. You will likely need to have another HLASM program to set the address space up to accept MODIFY commands in the first place. Thinking more about it, I might look at running an HLASM program as the main routine so that it can set up the environment properly as well as set up a SUBCOM environment. It would then invoke the IRXEXEC program to set up and run the REXX code. The REXX code could then use the ADDRESS xyz to get any pending data sent via the MODIFY command and process it. You could also use this same functionality to write to the operator console. The above is not simple. I am not aware of any builtin REXX facilities for z/OS console communications. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.

Re: F against a REXX STC
Instead of accepting command via console you can try using TCPIP. The IP API rexx exec sample members RSCLIENT and RSSERVER in TCPIP.SEZAINST or whatever TCPIP data set name your shop uses can be modified to do what you want. You can code your rexx stc to accept connection from a rexx client and receive a command from it. -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Zafiropoulos Konstantinos Sent: Thursday, November 03, 2005 7:26 AM To: IBM-MAIN@BAMA.UA.EDU Subject: F against a REXX STC Hi all, Can I send MVS modify command against a REXX that is running as an STC?

That sounds like an interesting approach, but accepting commands via TCP/IP has some major differences from accepting commands from an operator console. You have a much more restricted set of users who could give you a command when it has to come from an operator console, but anyone could send you a command via TCP/IP.

Re: F against a REXX STC
If the stc is doing serious tasks then proper coding is needed to examine the user who sends the command. Can RACF be used to restrict the client exec and port access? -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Walt Farrell Sent: Thursday, November 03, 2005 11:11 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Re: F against a REXX STC On 11/3/2005 11:24 AM, Kok, Howi wrote: Instead of accepting command via console you can try using TCPIP.

Can RACF be used to restrict the client exec and port access? No. RACF can secure a PORT in that it can disallow a server to listen on that port. However, RACF cannot do any validation for incoming connection requests. That would be up to the server to do. It appears, from my short reading, that the z/OS firewall technologies could be use to restrict incoming connection requests. But, as all things IBM, it appears to be complicated to set up. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
