Summary of ChangesNew in this Manual for VSE/POWER 6.4.0The following changes apply to functions addressed in this manual:RJE,BSC TraceThe decription of the RJE,BSC trace, formerly in Appendix E of VSE/ESANetworking Support, is now included in this manual. See Appendix D, “RJE,BSCTelecommunication Trace” on page 123.Alterable User InformationThe 16 byte user information field USER of JOB/LST/PUN statements can now be replaced by the "UINF " synonym to avoid confusion with the target user ID addressed by ALTER.,UINF. to– provide a TCP/IP address, or TCP/IP script file name, for list output– change generally the user information of job and output entries specified in a consistent way when placed in JECL statements or commandoperands interrogated for the currently executing job by the GETFLD macro from arunning programFour-Digit YearA four-digit year can be specified in the value of the CRDATE operand in theapplicable commands.Displaying Ignored InformationThe SHOWIGN parameter can be used with the START command to have a writertask print ignored CCWs and the start of the associated data. This option facilitatesdebugging.For a complete list of items.that are new in this version of VSE/POWER, please see the VSE/POWERAdministration and Operation manual.For a complete overview.of the functions which are new with VSE/ESA 2.4, refer to the IBM manualVSE/ESA Planning.

xviIBM VSE/POWER Remote Job Entry
IntroductionChapter 1. IntroductionThe RJE function of VSE/POWER lets you enter jobs for processing under VSE*from a remote terminal of one of the following ta Communication SystemData Transmission TerminalData StationData Communication SystemData Communication TerminalCommunication SystemOnce the job has been entered into the VSE/POWER files, it will be executed in thesame way as jobs submitted locally at the central host system.Binary Synchronous Communication (BSC) and System Network Architecture(SNA) terminal types are supported, and mixed configurations of both are possible.In general, all terminals and/or systems are supported which, for a BSC terminal,emulate the 2770, 2780, 3741, or 3780 line discipline and, for an SNA workstation,follow the rules defined for the 3770 and 3790.For information on compatibility, supported processors, programming requirements,storage requirements and calculations, and the generation of RJE support, refer toVSE/POWER Administration and Operation.The concepts of the various line disciplines are explained in thecorresponding component descriptions, as listed on page xii. While thesedevices are physically no longer produced, their handling is still described inthese manuals. This is to show how the RJE function of VSE/POWERcommunicates with these terminals according to their specific line discipline.RJE,BSC ConsiderationsWhen using the RJE function, you must consider the following: RJE input is limited to 128-byte records. The maximum print line width that can be specified for a 3741 is 132 byteswhen the expanded communication feature is installed, and 126 bytes without. To use 3770 terminals in BSC compatibility mode, the following specifications inthe PRMT macro are required:For 3771, 3773, 3774, and 3775 terminals, specify: TYPE 2770.For 3776 and 3777 terminals, specify: TYPE 2770 or TYPE 3780.If TYPE 2770 is specified, also specify: BE YES or ABE YES. RJE support in BSC mode for 3770 terminals requires components identicalwith those of the emulated terminal (2770 or 3780). The exception to this is theuse of a diskette.

IntroductionRJE,SNA FacilitiesVSE/POWER with RJE,SNA uses the VTAM application program interface (API) tohandle all line management with the SNA workstations that are attached to an IBM3704 or 3705 Communication Controller in NCP mode.The support for IBM 3770 SNA includes one logical printer, one logical punch, onelogical card reader, and one console with one active session.The functions provided in conjunction with the IBM 3790 Communication Systemwith RJE functions are: Concurrent Device OperationConcurrent processing of one inbound card-data stream, one inbound oroutbound message, and up to three outbound printers is supported. Host-to-3790 CompactionCompaction is a method for reducing the amount of data to be transmitted. Itimproves line utilization beyond the improvements ion. achieved bycompression. Compaction is supported for printer data only. Remote Data SpoolingRemote spooling is possible with appropriately equipped workstations, such asthe IBM 3790. VSE/POWER supports the transmission of a peripheral datastream information record (PDIR) that provides information pertinent to the joboutput requirements, such as a forms ID or the number of copies to beproduced. The benefits for the user result from the fact that functions are takenfrom the host processor to the workstation. For example, multiple copies of onedata stream need to be transmitted only once.For detailed information concerning the RJE,SNA I/O management and functions,refer to Appendix C of this book.Note: The default maximum print line width is 132 bytes and can be extended to512 bytes by using the MAXRECL operand in the PRMT macro definition(see VSE/POWER Administration and Operation).Terminal Operator FacilitiesThe terminal operator has the following means to control a system that uses theRJE function: Print and punch output operations can be interrupted to allow the terminaloperator to enter console, card, or diskette data. Commands can be keyed in at the terminal keyboard, entered on punchedcards through the card reader, entered in card-image format via magneticdiskette storage or via disk storage, whichever is available. User data can be entered from a card reader or from disk or diskette storage.VSE/POWER with RJE,SNA interprets all console/printer keyboard data asterminal operator commands.Using BSC terminals, user data may be entered via the console. However, notranslation to uppercase characters is performed by VSE/POWER.2IBM VSE/POWER Remote Job Entry
Introduction VSE/POWER SNA sessions can be terminated conditionally or unconditionally.Conditional session termination, using the conditional VTAM LOGOFFcommand or the VSE/POWER SIGNOFF command (which is alwaysconditional), permits active tasks to complete normally (until job boundary)before the terminal is disconnected. If the operator terminates his session bymeans of an unconditional VTAM LOGOFF command, any task that is currentlyactive for the terminal is canceled, and the terminal is disconnected from thesystem. In an SNA MLU environment, either all LUs or only selected ones of agiven workstation may be logged off. Diskette and disk storage devices are transparent to VSE/POWER; only theoriginating source is known to VSE/POWER, that is, it makes no difference toVSE/POWER if commands are entered directly from the terminal keyboard orindirectly via a diskette device. Also, input and output data formats are thesame, independent of direct or indirect data entry and independent of directoutput printing/ punching or indirect printing/punching in offline jobs aftertransmission to a diskette device.Machine RequirementsFigure 1 on page 4 lists the terminals, attachable I/O devices, and spoolingdevices that are supported by the RJE function.Chapter 1.
