High-Level Screen Management Intrinsic Library Reference Manual (32424-90002)

2- 2
Core Intrinsics. These intrinsics provide basic functionality.
HPDSEND Passes application data to the operator's
device and arranges it according to a
scheme identified or provided by the
application.
HPDREAD Collects data from the operator's device
and returns it to the application.
HPDPROMPT Lets the application focus the operator's
attention by altering and highlighting
data when it is displayed at the
terminal.
Supporting Intrinsics. These intrinsics provide supportive and
specialized capabilities.
Supportive Capabilities:
HPDOPENFORMS These intrinsics perform the housekeeping
HPDCLOSEFORMS duties of opening and closing forms, and
HPDENABLETERM enabling and disabling the terminal.
HPDDISENABLETERM
Specialized Capabilities:
HPDGETENV HPDSETENV These intrinsics let you see and set the values
for options in the execution environment. Use
them when your application requires a special
configuration.
HPDPRINTFORM Lets you obtain a printed copy of a form with
its data.
HPDGETDESIGN Lets you retrieve design information to
facilitate documenting your application.
HP32424 Lets you identify the current version of the
Hi-Li software.
The Hi-Li intrinsics and their parameters are described in detail in
Chapter 3.
The Hi-Li Model
Hi-Li is designed to control the transfer of data between the terminal
and an application with an interactive user interface. The data is
transferred as a block, rather than item by item. The sequence is as
follows.
The HPDSEND intrinsic sets up the form and displays it according to
