applications via intrinsics. The customer’s 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.
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.
* 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.
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 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.
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.
•
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 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.
•
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.
