the Optional Products section of this Software Product
Description.
Print Symbiont (OpenVMS Only)
The 3270 Application Services software provides a 3270
OpenVMS print symbiont for printing local ASCII files on
an SNA-attached LU Type 1 or Type 3 printer or a non-
SNA-attached LU Type 0 printer from an OpenVMS print
queue.
The 3270 OpenVMS print symbiont allows system man-
agers to initiate and start OpenVMS print queues. Users
can print files on SNA-attached printers. The following
features are available for OpenVMS users:
• Burst, flag, and trailer pages
• Print form specification
• Automatic session establishment, retry on error
• LU Type 1 printer console commands
• DCL queue management commands
Other features of the print symbiont include:
• Prints all types of sequential RMS files, including
FORTRAN and Print file types, except for non-PRN
VFC files.
• Data can be sent to the printer untranslated and un-
formatted. This is useful if the printer is an ASCII
printer attached to the SNA network. This is sup-
ported only for LU Type 1 printers.
• The symbiont can either pass through escape se-
quences or strip them out.
• Translation can be controlled on a queue-by-queue
basis. In this way, sites that need to use multiple
translation tables are accommodated.
• Certain IBM applications keep the printers bound un-
less they get a NOTIFY indication in the C(D)INIT.
Connections are now queued until the application un-
binds.
• The symbiont uses the FORM qualifier to set the size
of the margins. Text that goes beyond those margins
is truncated.
DECforms for 3270 Terminals (OpenVMS Only)
HP SNA 3270 Application Services provides support for
the DECforms (Version 1.4) product to enable the de-
velopment of forms-oriented applications that can be ac-
cessed by SNA networked 3270 terminal and PC users.
These DECforms applications can be developed with-
out knowledge of 3270 Data Stream, SNA, or the Com-
paq SNA Application Services software. DECforms is
Compaq’s implementation of the ANSI/ISO standard for
a Form Interface Management System (FIMS). Refer
to the DECforms Software Product Description (SPD
29.90.xx) for additional information.
Application Testing Tools
The HP SNA Domain Gateway is required for 3270 ac-
cess; however, a 3270 Terminal Emulator provides a
method for preliminary testing of incoming sessions by
emulating the SLU side of a session. For example, test-
ing can be done with the HP SNA 3270 Terminal Emu-
lator for OpenVMS (SPD 26.84.xx) or the HP DECwin-
dows SNA 3270 Terminal Emulator for OpenVMS (SPD
31.58.xx).
The HP SNA 3270 Application Services SNALOG trace
utility provides debugging facilities to debug applications
layered on HP SNA 3270 Application Services.
Thread Safe
Under Tru64 UNIX, the interface is fully thread safe and
can be used by a multithreaded program.
INSTALLATION
Installation services from HP are recommended for
a customer’s first purchase of this software product.
These services provide for installation of the software
product by an experienced software specialist.
