CICS Macro and Operand Descriptions This section describes CICS operands for the macros DFHTCT TYPE=TERMINAL and DFHTCT TYPE=SYSTEM.
WARNING The configuration values HP's SNA products require are in the tables that precede this section. Discussion of a specific value in the following pages does not imply that a particular HP SNA product can support that value.
DFHTCT TYPE=TERMINAL Macro The DFHTCT TYPE=TERMINAL macro defines the characteristics of an IBM 3270 LU and the CICS options that apply to the device supported by the LU. One DFHTCT TYPE=TERMINAL macro is coded for each LU. ACCMETH The value ACCMETH=VTAM specifies that a VTAM TCT terminal entry (TCTTE) is to be generated. BUFFER Specifies the size of the buffer that the remote LU uses to receive a Request Unit (RU) from CICS. Messages longer than the size of BUFFER are segmented into a number of RUs that are chained together for recovery purposes. Default: 256 Range: 810-1536 CHNASSY Specifies whether chains are to be assembled on input by terminal control before any processing is performed on any part of the chain. Default for LU.T2: YES Default for LU.T1 and LU.T3: NO ERRATT Specifies attributes of the error message line. Default: NO FEATURE Code this operand with the features that apply to the LU being emulated. The features found in tables 3-1 through 3-3 are described below. AUDALARMspecifies the IBM 3270 audible alarm feature. COLORspecifies the extended color feature which allows colors to be selected for each field or character. EXTDSspecifies extensions to the IBM 3270 data stream. HILIGHTspecifies the extended highlighting feature. This enables fields or characters to be displayed in reverse-video, underline mode, or blink. SELCTPENspecifies the Selector Pen feature--allows the Cursor Select feature. Not used by CICS--simply provides information to application programs that require information about a particular device's available features. FF Specifies whether the LU supports the SCS Forms Feed (FF) control character. Default: NO GMMSG Specifies whether the CICS "good morning" message will be displayed when the logical unit is signed on to VTAM. If you have specified ERRATT=LASTLINE, the "good morning" message will not overwrite the error message line. Default: NO HF Specifies whether the LU supports the SCS Horizontal Format (HF) feature. Default: NO NETNAME Specifies a one-to-eight character symbolic name, which is the LUname specified for this LU in the NCP/VTAM generation. The value of NETNAME must match the network name of the LU specified at the start of the LU macro. Default: The value of TRMIDENT padded with four trailing blanks. PGESTAT Indicates the type of paging activity that occurs at a given terminal. AUTOPAGEindicates that a number of pages can be sent as a chain, without a response from the LU after each page. Default: AUTOPAGE RELREQ The first field specifies whether CICS can release the LU if it is not currently active in a transaction. The second field indicates whether CICS honors a disconnect request from the LU. A CSSF LOGOFF or GOODNIGHT from the terminal will also cause disconnection if YES is specified in the second field. Default for first field: NO RUSIZE Specifies the size of the RU that can be sent from the LU to CICS. Default: 256 Range: 10-256 TCTUAL Specifies a user area length for this terminal. The TCT user area is initialized to zeros at system initialization time. System dependent, this operand may be used by application and/or system level routines as required at your IBM installation. TIOAL Used in conjunction with CHNASSY=YES. Specifies a normal chain size and a maximum chain size. DFHZCP initially acquires a TIOAL of normal chain size to satisfy a transaction RECEIVE request. If the normal chain size is not large enough, a larger TIOAL will be acquired, limited by the value of maximum chain size. TRMIDNT Specifies a unique four-character symbolic identifier (name) for each terminal. The value of NETNAME defaults to the value of TRMIDNT padded with four trailing blanks. TRMMODL Specifies the model number of the terminal. A number of other operands, such as DEFSCRN and ALTSCRN, default to the screensize value associated with TRMMODL. TRMTYPE This operand must be coded with the keyword that specifies the kind of device the LU supports. TRMSTAT The value for this operand specifies the types of activity that may occur at a terminal. TRANSCEIVEspecifies that a given terminal can initiate transactions and receive messages. RECEIVEindicates that a terminal can receive messages, but cannot accept input. Default: TRANSCEIVE VF Specifies whether the LU supports the SCS Vertical Format (VF) feature. Default: NO DFHTCT TYPE=SYSTEM Macro The DFHTCT TYPE=SYSTEM macro is used to define the characteristics of an LU type 6.2 and the CICS options that apply to the application supported by the LU. One DFHTCT TYPE=SYSTEM macro is coded for each LU type 6.2. ACCMETH The value ACCMETH=VTAM specifies that a VTAM TCT terminal entry (TCTTE) is to be generated. BUFFER Specifies the size of the buffer that the remote LU uses to receive an RU from CICS. CICS messages longer than the size of BUFFER are segmented into a number of RUs that are chained together for recovery purposes. Default: 256 Range: 10-1536 FEATURE Specifies applicable features for a given device. SINGLE specifies that an LU type 6.2 terminal is supported on a single session with CICS. Coding this value causes CICS to generate a DFHTCT TYPE=TERMINAL macro which is automatically combined with the DFHTCT TYPE=SYSTEM macro. NETNAME Specifies a one-to-eight character symbolic name, which is the LUname specified for this LU in the NCP/VTAM generation. NETNAME must match the network name of the LU specified at the start of the LU macro. Default: The value of SYSIDNT, padded with four trailing blanks. RUSIZE Specifies the maximum size RU that can be sent from the LU to CICS. Default: 256 SYSIDNT Specifies a unique four-character symbolic identifier for each terminal. If you do not supply a NETNAME, then NETNAME defaults to SYSIDNT. SYSIDNT must in turn satisfy the requirements of NETNAME. TRMTYPE Specifies the type of system being connected to CICS. LUTYPE62 specifies that this is an LU type 6.2 intercommunication link. TRMSTAT Specifies the types of transactions that can occur at a given terminal. TRANSCEIVEindicates that the terminal can initiate transactions, and that it can receive messages. Default: TRANSCEIVE Resource Definition Online Resource Definition Online (RDO) allows a system programmer to interactively define resources to CICS. The system programmer can install RDO definitions as CICS system tables, by specifying a list of definitions at system initialization time. The system programmer can also install these definitions while CICS is running, so that they can be used immediately. Table 3-5lists the macros and operands used to define resources in a Terminal Control Table, and lists the corresponding RDO keywords used to define those resources. Table 3-5.
