L A Programmer’s Guide to VPLUS
VPLUS is an HP tool used by programmers to design screens and implement an on-line
application to collect and display information. With VPLUS, you are able to design screens
which prompt the user for input in familiar business terms. VPLUS intrinsics are
available to help you develop a customized application.
This note is intended for programmers who want to understand the purpose of each
intrinsic and the sequence of calls. For each intrinsic, a discussion of the passed
parameters, some programming tips, and some details of what the intrinsic does is
presented. Also included is a summary of VPLUS enhancements which can make an
existing or new application easier to use. A brief synopsis is presented on each
enhancement. For more details on their use, please refer to the HP Data Entry and Forms
Management System (VPLUS/V) Reference Manual. Note that in the remainder of this
paper, this manual will be referred to as the VPLUS/V Reference Manual.
This Application Note covers two topics to help you code your application.
• VPLUS Intrinsic Calls
• VPLUS Enhancements
This note assumes that the reader has some basic knowledge of the HP Data Entry and
Forms Management System (VPLUS).
