The Output Management feature of SNA  
NRJE allows users to have job output routed  
based on the form selected by the users 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.

applications via intrinsics. The customers application  
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.  
In the programmatic mode, user-written programs on  
the HP 3000 can communicate with programs on the  
host. HP 3000 programs may be written in C,  
FORTRAN, COBOL, COBOL II, BASIC, Pascal, or SPL.

Program access is accomplished through use  
of a set of intrinsics that are powerful  
procedures, which perform the low-level task  
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

HP LU 6.2 API implements the LU 6.2 “mapped  
conversation verbs” for what IBM has named “advanced  
program-to-program communications” (APPC). Users  
may write “transaction programs” that use these verbs  
(or high-level intrinsics as HP has implemented them) in  
order to communicate with each other, even though  
these programs may be executing on different systems  
within the SNA network.

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.  
• Efficient and easy-to-program problem  
detection and recovery procedures.  
• As with all HP SNA services, customized  
error and help facilities are provided.  
X.25 Connectivity: HP LU 6.2 API/iX can  
communicate to an IBM mainframe over an  
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  
to go through a mainframe node.  
Parallel Sessions: With MPE/iX Release  
4.0 or later, LU 6.2 API/iX provides support  
for parallel sessions over Node Type 2.1. An  
HP 3000 may establish multiple, simultane-  
ous LU-LU sessions over a single LU-LU pair  
over Node Type 2.1.  
Support for Remote Attach: Remote  
Attach is the ability of a remote LU 6.2  
application to start running and begin com-  
munication with it.  
Compatibility with Other SNA  
Services: The HP LU 6.2 API is completely  
compatible with other SNA services offered

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  
Other HP SNA Service products are  
supported over the same SNA Link;  
each SNA Link can support up to  
64 Logical Unit (LU) sessions. The  
maximum line speed supported by  
SNA Link is 64 KB/s.

When the VPLUS forms have been designed  
and are ready to be compiled, the applications  
designer will select the “IBM 3270” box in the  
Terminal Selection Menu of FORMSPEC, in  
addition to any HP terminal options normally  
selected, in order to include the IBM 3270  
format in the VPLUS forms file. Please note  
that, in an existing application, some VPLUS  
forms may need to be modified due to  
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 users 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 Programmers  
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  
IBMs 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.
