A set of callable intrinsics is provided by VPLUS. Table 6-1 “Summary of VPLUS Intrinsics” lists the VPLUS intrinsics in alphabetic order and
summarizes their functions. A full description of each intrinsic appears
later in this section. They can be used by any application, either
for data entry or for other terminal related applications. The VPLUS
intrinsics manage the interface between an application, the terminal,
a forms file, the entered data, and, optionally, the batch file
to which entered data may be written. These intrinsics are used
by the VPLUS Data Entry Program (ENTRY) to control data entry.
Appendix A contains listings in different programming languages
of sample applications. These listings provide useful examples of
how to use the VPLUS intrinsics.
