HPDSETENV
Allows your application to configure elements of the current execution
environment.
Syntax
HPDSETENV globalpak, returnpak, mode, envbufdescrpt, envbuf
Parameter Descriptions
globalpak A compound parameter that passes information
between intrinsics. For a complete description
of this parameter, see "Global Parameters" in
Chapter 3.
returnpak A compound parameter that passes information
back from the intrinsic to the application.
For a complete description of this parameter,
see "Global Parameters" in Chapter 3.
mode A four-byte integer returned to the intrinsic
that specifies the element in the execution
environment that you want to configure. The
values you can specify are:
2 = native language identifier
3 = auto test option
78 = switch device out of block mode
79 = switch device into block mode
envbufdescrpt A four-byte integer that is input to the
intrinsic. Use this parameter for those cases
when your application is allowed to specify the
size and arrangement of the configuration
update passed in the envbuf parameter.
Note: The input format of most of the
available configuration updates is fixed. If
this is the case, this parameter is ignored.
envbuf A compound parameter that is input to the
intrinsic. It defines the area that contains
the configuration update. The value you supply
for this parameter depends on the mode you have
specified:
(If) (Supply)
Mode Element Length/format
---------------------------------------------------------------------------------------
2 Native language A four-byte integer that specifies the language conventions
to be used. To use this feature, the forms file must be
open and your application must ensure the following:
- An "international" forms file is currently being accessed.
- Native language subsystem software is installed on the
system you are using.
- The native language you are requesting must be on the
system. See the Native Language Support Reference Manual
(Part No. ?) for the language codes that you can use.
3 Auto test option A four-byte integer that sets up automatic terminal
interaction. To use this mode, the forms file must have
been opened or the device enabled. The values you can
supply are:
0 = disable
1 = enable
78 Switch out of An 88-byte character array that is the name of the device
block mode file you want to switch out of block mode. To use this
mode, the device must have been enabled by HPDENABLETERM.
79 Switch into block An 88-byte character array that is the name of the device
mode file you want to switch into block mode. To use this
feature, the device must have been enabled and switched out
of block mode.
Discussion
HPDSETENV is designed for advanced programming applications. It allows
you to configure various elements of your application's current execution
environment. You can configure four elements in your application's
environment. You can:
1. Configure the native language identifier so that prompts and data
editing follow the conventions of a particular language.
2. Turn on the auto test feature so that your application can execute
without someone having to be at the terminal. One possible use of
this feature is for automatic test suites.
3. Momentarily switch a device into
4. - or out of block mode.
