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 HPÕs Network Services.

¥SNA IMF/iX supports HPÕs 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:

ÐSNA IMF/iX (ASIAN) supports IBMÕs DBCS protocol to ensure 16- bit data integrity communication between the HP 3000 and the Asian host.

ÐSNA IMF/iX (ASIAN) allows both 16-bit interactive as well as programmable access to the Asian IBM host.

ÐSNA IMF/iX (ASIAN) provides 16- bit character mapping between the HP (HP-15) and the IBM (DBCS) data.

ÐSNA IMF/iX (ASIAN) supports languages such as Japanese, Korean, and Traditional Chinese.
