The IMS installation macro operands for the TYPE and TERMINAL macros allowed for HP SNA products are described below.

NOTE: See the IMS installation manual for your system for a more thorough explanation of the macros and their values.

TYPE

Defines the SNA LU type. The TYPE macro contains all TERMINAL and NAME macros until another TYPE macro appears.

UNITTYPE=

Specifies the LU type for all TERMINAL macros defined under this TYPE macro:

SLUTYPE1Specifies LU type 1. This must be specified for LU.T1 and LU.T3 printers.
SLUTYPE2Specifies LU type 2. This must be specified for LU.T2 and LU.2X terminals.

TERMINAL

Defines the characteristics of a 3270 LU and the IMS operations that apply. A TERMINAL macro isspecified for each 3270 LU. Unless otherwise noted, each operand applies to both keyboard/displays and printers.

NAME=luname

Specifies a one-to-eight character name (luname), which is the LU name specified for this LU in the NCP/VTAM generation. Do not specify LINE or ALL as luname.

MODEL=2

Specifies a display screen or print buffer size of 1920 characters. For other screen or buffer sizes, see the IMS installation guide for your system.

MSGDEL=NOTERM

Specifies that IMS/VS should discard DFS059 TERMINAL status messages and DFS2002 TERMINAL CONNECTED status messages for this terminal.

FEAT=(PFK,NOCD)

Specifies that program function keys (PFKs) are available on this keyboard.

Default: (PFK,CARD,PEN)

OUTBUF=bufsize

Specifies the size of the IMS output buffer to be used to pass a Request Unit (RU) to VTAM. For a keyboard/display, this buffer contains the 3270 commands and data for a single 3270 screen (or portion to be updated). This value can be used by IMS to establish the BIND. If it is specified incorrectly, it could cause rejection of the BIND by the device.

Range: 256- 32000

Recommended Value for LU.T1: size of average print session

Recommended Value for LU.T2 and LU.T3: 1536

Default: 2000

OPTIONS=

Specifies whether IMS can initiate the screen print ("local copy") feature. This function is dependent upon whether an LU type 1 printer has been configured in NCP/VTAM and IMS:

COPYThe printer is configured. Note that the printer must be attached to the same cluster controller as the keyboard/display.
NOCOPY

The printer is not configured.

Default: COPY
