The Output Management feature of SNA
NRJE allows users to have job output routed
based on the form selected by the user’s host
JCL and a Lookup Table which provides a
mapping between host form names and HP
3000 file equations. Again default forms will
be used if none are indicated.
Product Requirements
Both SNA NRJE/iX and SNA NRJE/V require an
IBM System/370-compatible mainframe (Model
370, 30xx or 43xx) with an IBM 37xx
communications controller. The following
software must be running on the host and
communications controller:
Reverse NRJE allows a user connected to an
IBM mainframe (or a user on a separate HP
3000 attached to the IBM) to start a job on an
HP 3000 if SNA NRJE on the HP 3000 is
active.
• Job Entry Subsystem: JES2 or JES3
running under
– Operating System: MVS
or
• Job Entry Subsystem: VSE/POWER
running under
– Operating System: VSE
– ACF/VTAM
Note: The user must use the special form
CMD that causes SNA NRJE to stream a
received data set rather than route the data
set using file equation attributes.
– ACF/NCP
Using SNA NRJE and SNA Link, an HP 3000
with an HP 2680 Laser Printer can act as a
remote or local (though still requiring a 37xx
communications controller) print station for
an IBM host. HP 3000 users can direct print
output data sets to the laser printer. Users
can specify an environment file that indicates
predefined forms, character fonts and formats
- data set by data set.

Features
SNA IMF/iX Interactive
Mainframe Facility
•
•
•
SNA IMF/iX and an SNA Link product
allow the HP 3000 to emulate the base
function set of an IBM 3270 control unit
using SNA (PU2 or 2.1, LU1, 2, 3)
protocols.
The SNA Interactive Mainframe Facility/iX (SNA IMF/iX)
product provides IBM 3270 device emulation for
Hewlett-Packard terminals, printers, and HP 3000 Series
900 systems. (SNA IMF/V, P/N 30247A, provides similar
functionality for MPE V systems.)
Other HP SNA service products can all
be supported simultaneously over one
SNA/SDLC Link/iX or SNA/X.25 Link/iX.
The maximum datacomm line speed is
64 KB/s.
SNA IMF/iX on an HP 3000 Series 900 allows interactive
communications between the HP 3000 and an IBM
System/ 370-compatible mainframe using SNA 3270
protocols. SNA IMF/iX emulates the base function set of
an IBM 3270 control unit using SNA Physical Unit Type
2 (PU2 or 2.1), Logical Unit Types 1,2,3 (LU1, 2,3)
protocols. HP terminals, printers, and applications on
the HP 3000 running SNA IMF/iX emulate IBM terminal
and printer functions.
SNA IMF/iX supports up to 127 devices
(terminals, printers, and application
programs) concurrently. With MPE/iX
Release 4.0 or later, SNA IMF/iX
supports up to 127 devices per SNA Link.
•
•
The Pass Thru capability of SNA IMF/iX
allows HP 3000-attached printers and
terminals to emulate the base function
set of IBM 3270 printers and terminals.
SNA IMF/iX allows access to 3270 subsystems on the
mainframe (such as TSO, CICS, and IMS) through a set
of high-level intrinsics. There are two modes of
operation. In programmatic mode, customer-written
application programs on the HP 3000 emulate IBM 3270
terminals and printers, exchanging data with the host
SNA IMF/iX Pass Thru takes advantage
of the Modified Data Tag feature of
selected HP terminals (such as the HP
700/94) and supports a write
optimization feature that limits screen
updating to modified rows only. These
features significantly reduce response
time.

program decides which intrinsics to call. In Pass Thru
mode, an HP-written application program on the HP
3000 also emulates IBM 3270 terminals and printers,
exchanging data with host applications via intrinsics. In
Pass Thru mode, the selection of which intrinsics to call
is fixed.
Features (continued)
•
SNA IMF/iX allows programs on an
HP 3000 to communicate with
programs o the host system, through
a set of high-level intrinsics.
Programs may be written in C,
FORTRAN, COBOL, COBOL II, BASIC,
Pascal, or SPL.
SNA IMF/iX requires the installation and use of
SNA/SDLC Link/iX (30291B), SNA/Token Ring Link/iX
(J2167B)* or SNA/X.25 Link/iX (36939B). The SNA
Link products manage the physical link to the host and
implement protocols in the lower three layers of SNA.
•
•
•
Most host application programs
designed to work with IBM 3270
terminals can usually be used with
minimal change.
SNA IMF/iX runs concurrently with
other HP 3000 applications and can
be accessed from other systems via
HP’s Network Services.
* SNA/Token Ring Link/iX (J2167B) requires MPE/iX
release 5.5 Express 7 or later, or MPE/iX release 6.0
Express 1 or later.
SNA IMF/iX supports HP’s Native
Languages Support (NLS 8-bit
character mapping), which allows
application programmers to create
local language applications for end
users. NLS 16-bit character mapping;
interactive and programmatic access;
and data integrity are not supported
for languages such as Japanese,
Korean, Simplified Chinese, and
Traditional Chinese.
Asian options also supported include:
• HP Asian Vectra PCs
• HP Asian Terminals
• HP Asian Printers
• Asian IBM environments
Functional Description
SNA IMF/iX is a software product that allows an
HP 3000 and attached devices to emulate the base
function set of an IBM 3274 control unit and attached
devices, which does not include graphics, programmed
symbols, color, or extended highlighting.
•
•
SNA IMF/iX supports IBM applications
with 480, 1920, or 3440 character
screen sizes.
For Asian options only:
–
SNA IMF/iX (ASIAN) supports
IBM’s DBCS protocol to ensure 16-
bit data integrity communication
between the HP 3000 and the
Asian host.
SNA IMF/iX (ASIAN) allows both
16-bit interactive as well as
programmable access to the
Asian IBM host.
SNA IMF/iX (ASIAN) provides 16-
bit character mapping between
the HP (HP-15) and the IBM
(DBCS) data.
SNA IMF/iX (ASIAN) supports
languages such as Japanese,
Korean, and Traditional Chinese.
SNA IMF/iX requires SNA/SDLC Link/iX, SNA/Token
Ring Link/iX or SNA/X.25 Link/iX. These links manage
the communications link and implement lower-level SNA
(PU2 or 2.1) protocols. SNA IMF/iX provides interactive
and programmatic 3270 communications with a
mainframe and can run simultaneously along with other
SNA services such as SNA NRJE/iX and LU6.2 API/iX on
MPE/iX systems.

of decoding the data streams.
written for use with IBM 3270 controllers will
work with SNA IMF/iX with little or no
modification. For customers who are in the
process of changing from centralized to
distributed processing, this feature helps
provide a smooth transition.
(Table 1 provides a list of available intrinsics.)
The intrinsics can be used with the intrinsics
of other HP 3000 facilities such as
IMAGE/3000, VPLUS/3000, KSAM/3000, or
NS/3000. The high-level, easy-to-use nature
of these intrinsics results in improved
programmer productivity.
The Pass Thru mode of SNA IMF/iX provides
users the capability of using HP 3000 attached
printers and DTC attached terminals for
interactive access to a host computer.
In this mode, SNA IMF/iX users can directly
access host software such as CICS or IMS, or
they can use TSO for program development.
Because programmatic mode works by
exchanging information through screen
images, most host applications that have been

For HP terminals being used in the Pass Thru
mode, the response time will be longer than
that of IBM terminals:
• The data transmission rate between the
HP 3000 and the terminals is slower than
that between the IBM 3270 controller and
its attached terminals.
• For terminals not supported by the write
optimization feature, the screens on the
HP 3000 and Pass Thru terminals are
rewritten any time a change is made. For
small changes, this contributes to an
increase in response time
• SNA IMF/iX uses the Modified Data Tag fea-
ture of the HP 700/94, HP 2394A, and HP
150 terminals in order to accurately and
flexibly handle null and blank characters. In
addition, this may result in improved
response time when compared to other HP
terminals.

• Although the principle functions of IBM
3270 terminal keyboards are implemented -
including Program Function (PF) keys and
Program Attention (PA) keys - there are
some differences:
unprotected field by replacing the field with
exactly the same characters as it had previ-
ously; the field would NOT be transmitted
to the host with SNA IMF/iX, since no char-
acters had changed. A real 3270-type ter-
minal will transmit such modified fields
whether or not any characters are actually
changed.
• Some keys are in different positions, some
keys have different labels, and some keys
are not implemented. Table 2 lists the
major differences between IBM 3270 termi-
nals and HP 2392 terminals.
• Leading blanks can be converted to nulls
based on a configuration option at Pass
Thru startup.
• Trailing blanks can be converted to nulls
based on a configuration option at Pass
Thru startup.
• Trailing nulls can be converted to blanks
based on a configuration optional Pass Thru
startup.
• Magnetic card reader, auxiliary card reader,
and light pen are not provided in HP termi-
nals using Pass Thru mode.
There are minor logical differences in the way
HP terminals behave. Differences include:
• With Pass Thru mode, only unprotected
fields in which one or more characters have
actually been changed are transmitted to
the host. If a Pass Thru user “modifies” an

for the HP 3000. These HP SNA products
may all be running simultaneously over the
same SNA Link/V, SNA/SDLC Link/iX,
SNA/Token Ring Link/iX* or SNA/X.25
Link/iX to the SNA network. The SNA Link
products manage the physical link to the
IBM host and implement protocols in the
lower three layers of SNA.
HP LU 6.2 API provides
• High-level Intrinsics: HP 3000 program-
mers can use a set of high-level intrinsics to
implement program-to-program communica-
tion in an SNA network.
• Support for Major Languages:
Application programs on the HP 3000 can
be written in COBOL II, Transact, or Pascal.
For LU 6.2 API/iX, C language applications
are also supported.
• Support for IBM Applications: HP LU
6.2 API supports Mapped Conversations
with CICS in an MVS or DOS/VSE environ-
ment and Mapped Conversations with
VTAM in an MVS environment. With
MPE/iX Release 4.0 or later, HP LU 6.2
API/iX supports Mapped Conversations in
an OS/400 environment.
• Multiple Sessions: An HP 3000 applica-
tion program using LU 6.2 API/V intrinsics
may have up to 8 LU-LU sessions running
simultaneously. With MPE/iX Release 4.0 or
later, an HP 3000 application program using
LU 6.2 API/iX intrinsics may have up to 256
LU-LU sessions running simultaneously.
Each session is responsible for a separate
communication task or for adding additional
bandwidth to a single communication task.
• Peer-to-peer Connectivity: With MPE/iX
Release 4.0 or later, LU 6.2 API/iX provides
peer-to-peer connectivity to an IBM
Note: HP LU 6.2 API/iX supports Native-
mode HP 3000 applications only.
• Trace Facility: An easy-to-use trace facili-
ty that allows HP 3000 application program-
mers to track all LU 6.2 intrinsic calls and
executions within applications being devel-
oped, serving as a valuable debugging aid
during program development.
• Logging Facility: A comprehensive logging
facility that records all online LU 6.2 API
session messages to aid in problem identifi-
cation and resolution.
• User Controlled Sessions Management
from Program or CI ( CNOS) : With
MPE/iX Release 5.5 Express 7 or later, or
MPE/iX Release 6.0 Express 1 or later,
Programmatic or interactive user-controlled
session management allows users to change
session limits (over Node Type 2.1).
• Enhanced Communication Rates: The
maximum datacomm line speed between
the HP 3000 and the IBM mainframe host is
56 KB/s on MPE V and 16 MB/s on MPE/iX.

X.25 connection. The SNA/X.25 Link/iX
product (HP 30298A) can be used in place
of SNA/SDLC Link/iX, or SNA/Token Ring
Link/iX* but SNA/X.25 Link/iX emulates a
Type 2.0 node, not a Type 2.1 node.
Therefore if you run LU 6.2 API/iX over
SNA/X.25 Link/iX, you cannot communicate,
peer-to-peer with a Type 2.1 node like an
IBM AS/400.
AS/4000 over Node Type 2.1. an HP 3000
may establish LU-LU sessions with an IBM
AS/400 over Node Type 2.1 without having

LU 6.2 API intrinsics are summarized in the
following table.
Functional Description
HP LU 6.2 API provides a set of high-level
intrinsics for application programmers to use
for program-to-program communication
between an HP 3000 application program and
an application program running on an IBM
host mainframe. HP LU 6.2 API/iX also pro-
vides communication to an IBM AS/400.
These intrinsics are responsible for initiating
LU 6.2 conversations so that data can be sent
or received over these conversations on behalf
of program pairs needing to communicate to
complete a “transaction.” Examples of trans-
action are database updates and file transfers.
LU 6.2 API consists of a set of user-callable
intrinsics that implement the set of LU 6.2
defined mapped verbs along with the follow-
ing option sets:

SNA Distributed Host Command Facility
•
•
•
SNA DHCF/iX provides IBM 3270
display stations with HP terminal
capabilities including support for TTY-
mode (simple ASCII) applications and
many VPLUS applications.
VPLUS has been optimized for
applications used with SNA DHCF/iX;
VPLUS forms can be compiled into
IBM 3270 terminal formats prior to
runtime.
SNA DHCF/iX provides HP terminal
emulation support for screen sizes of
24, 32, or 43 lines for TTY-mode
applications. VPLUS applications are
supported with screens of up to 24
lines less any lines required for a
window line or softkeys.
In VPLUS applications, SNA DHCF/iX
supports HP terminal softkeys (as PF
keys) and a “window” line on IBM
3270 display stations using the
bottom three lines of the screen.
One MPE/iX session is provided for
every SNA DHCF/iX user; each SNA
DHCF/iX session appears as a
Network Services Virtual Terminal
(NS VT) session.
The HP SNA Distributed Host Command Facility/iX (HP
SNA DHCF/iX) software product provides IBM mainframe
users who use IBM 3270 display stations with interactive
access to an HP 3000 Series 900 system. Together with
the IBM Host Command Facility (HCF Version 2) product
on the IBM mainframe system, SNA DHCF/iX gives IBM
3270 display station users the capability to run many
applications on the HP 3000 system. These applications
include TTY-mode and VPLUS applications.
SNA DHCF/iX provides the data conversion services that
translate output between applications on the HP 3000 and
the IBM 3270 datastream required by IBM display stations.
SNA DHCF/iX enables IBM 3270 display station users to
access the HP 3000 system over their existing SNA, Token
Ring, or X.25 network. SNA DHCF/iX requires the
installation and use of the SNA/SDLC Link/iX (30292B and
A5563A), SNA/Token Ring/iX (J2167B)*, or the SNA/X.25
Link/iX (36939B) product (referred to jointly as SNA
Link). SNA Link products manage the physical link to the
IBM mainframe and implement the datacomm protocols in
the lower three layers of SNA.
•
•
* SNA/Token Ring Link/iX (J2167B) requires MPE/iX
release 5.5 Express 5 or later, or MPE/iX release 6.0
Express 1 or later.
•
•
SNA DHCF/iX supports the HP “Break”
and “Control-Y” keys.
SNA DHCF/iX can support up to 64
simultaneous sessions per SNA Link
node. Using multiple SNA Link nodes,
SNA DHCF/iX’s session count is
limited only by the number of LDEVs
available on the HP 3000

limitations of the IBM 3270 display station.
Many of the VPLUS forms may require no
changes.
Functional Description
HP SNA DHCF/iX is a software product that
provides an IBM 3270 display station with
access to applications on an HP 3000. SNA
DHCF/iX emulates many features of a
remotely attached HP terminal; thus, it
appears as if the IBM 3270 display station has
a direct connection to the HP 3000 computer.
SNA DHCF/iX can be operated across an
existing SNA or X.25 network.
SNA DHCF/iX communicates with Host
Command Facility (HCF) on the IBM
Usage Considerations
mainframe in order to exchange data between
the user’s MPE session and the IBM terminal.
To the HP 3000 system, each SNA DHCF/iX
session appears as a NS VT session. For IBM
3270 display stations, SNA DHCF/iX provides
access to two primary groups of applications
on the HP 3000 Series 900 system.
HP SNA DHCF/iX is not a complete
replacement for HP terminals such as the HP
700/92 and HP 700/94 terminals. Due to
limitations of the IBM 3270 display station,
SNA DHCF/iX cannot support all HP 3000
applications. In addition, some HP 3000
applications may require modifications prior
to use with SNA DHCF/iX. Please refer to the
SNA DHCF/iX Application Programmer’s
Guide for information on usage considerations
discussed here.
• TTY-mode applications are characterized by
their simple use of terminal control charac-
ters (carriage return, line feed, form feed,
tab, bell). SNA DHCF/iX translates the data
as output being sent to the IBM terminal.
This group of applications includes the basic
MPE/iX CI (Command Interpreter) com-
mands.
The HP keyboard differs from the IBM
keyboard. The chart below shows some
differences.
HP Terminals
HP Function Keys
IBM Terminals
IBM PF Keys 1-8 (VPLUS
Applications only)
• VPLUS applications are characterized by
the use of the VPLUS forms subsystem that
is included with the MPE FOS. VPLUS has
been enhanced so that an applications pro-
grammer can design VPLUS-based applica-
tions for the IBM 3270 display station in
addition to other HP terminals.
Consequently, IBM 3270 display station
users can be provided with access to many
VPLUS-based applications using SNA
DHCF/iX.

When developing VPLUS applications for use
with SNA DHCF/iX, the application designer
can develop and modify VPLUS forms using
techniques similar to those for HP terminals.

HP 3000 applications that use special screen-
mode or block-mode features that are specific
to HP terminals are not supported. Some of
these restrictions include:
If the target application violates any of these
restrictions, then it is not supported by SNA
DHCF/iX. An error condition will be returned
to the application when an unsupported
feature is used. Prior to installation of SNA
DHCF/iX, target HP 3000 applications should
be qualified to ensure that they meet these
restrictions.
• HP terminal escape sequences used for cur-
sor positioning, terminal strap settings, pro-
grammable softkeys, etc.
• Screen enhancements such as inverse video,
blinking, underlining, etc.
When using SNA DHCF/iX, IBM 3270 display
station users may experience different
performance and functionality than HP
terminal users. For IBM 3270 display stations,
response times may be somewhat greater than
an HP terminal due to the SNA network
overhead.
SNA DHCF/iX can provide universal access to
HPDESK for an integrated office automation
solution.
Within VPLUS applications, SNA DHCF/iX
supports all of the VPLUS intrinsics except for
VPRINTSCREEN and VPRINTFORM. Due to
limitations of the IBM 3270 display station,
VPLUS forms caching is not supported with
SNA DHCF/iX. In addition, several points
need to be considered in VPLUS forms design
including:
Functional Specifications
• SNA DHCF/iX supports many of the basic
functions of HP terminals. Please refer to
the Usage Considerations section for fea-
tures that are not supported. Supported fea-
tures include:
• Prior to using a VPLUS application with
SNA DHCF/iX, the VPLUS forms file must
be recompiled using the ‘IBM 3270’ terminal
option.
• When using FORMSPEC to design VPLUS
forms, an HP terminal such as the HP
700/94 is required.
• Unlike HP terminals, IBM 3270 display sta-
tions require an actual space on the screen
for an attribute byte that describes the
attributes of the following field.
• Each field on the IBM display station needs
to be preceded by this attribute byte; conse-
quently, back-to-back fields are not allowed
on the IBM 3270.
– Modified Data Tags
– Security Fields
• SNA DHCF/iX supports three different dis-
play enhancements for IBM 3270 display
stations: full-bright, half-bright, and non-dis-
play. (Non-display is for security fields.)
• SNA DHCF/iX supports those IBM devices
officially supported by IBM for the Host
Command Facility, Version 2. Please refer to
IBM’s HCF Product Specification Guide
(GC27-0647) for a complete listing.
• Each SNA DHCF/iX session appears as a
Virtual Terminal session. The pool of Virtual
Terminal sessions available for other users
will be reduced by the number of SNA
DHCF/iX sessions that are currently active.
• SNA DHCF/iX can support multiple simulta-
neous sessions, depending upon the number
of VT sessions or LDEVs (depending on the
MPE/iX release) distributed across multiple
SNA Links.
• With SNA DHCF/iX, a VPLUS form can have
at most 24 lines; if features such as softkeys
(two lines) or a window line (one line) are
used in the application, then the available
lines for the form are reduced by the num-
ber of lines required by these features.
• Each SNA Link can support up to 64 con-
current sessions distributed among the vari-
ous SNA/iX services.

• Using an HP 3000 Series 900 and SNA
DHCF/iX as a gateway system, IBM 3270
display stations can access only TTY-mode
applications on other HP 3000 MPE/iX sys-
tems. Access to other systems requires the
NS Network Service and Link products.
• SNA DHCF/iX supports “reverse VT” func-
tionality; this permits an HP application to
acquire remote IBM 3270 display stations
provided that the SNA DHCF/iX session has
already been established.
HP will support certain versions and later
releases of the above software. Your HP
support representatives must determine
whether SNA DHCF/iX can be supported with
your network configuration. The Network
Implementation Support Plan (NISP) will
assist the HP account team in determining
support requirements prior to the installation
of SNA DHCF/iX.
