- 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.
AUDALARM
IBM 3270 audible alarm feature.
COLOR
value specifies the extended color feature which allows colors
to be selected for each field or character.
EXTDS
specifies extensions to the IBM 3270 data stream.
HILIGHT
extended highlighting feature. This enables fields or characters to
be displayed in reverse-video, underline mode, or blink.
SELCTPEN
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.
AUTOPAGE
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.
TRANSCEIVE
that a given terminal can initiate transactions and receive messages.
RECEIVE
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
