Entering Data with ENTRY
Protected and Unprotected Fields
2 Entering Data with ENTRY
This chapter describes using the VPLUS standalone data entry application, called ENTRY.
The forms file you design implements the specific data collection function that your
application requires. ENTRY is the execution mechanism.
This chapter is intended for the operator of the ENTRY program. Since ENTRY is written
using the VPLUS intrinsics, you can also use this chapter as a tutorial that explains some
of the concepts you might apply when designing your own application program. If a locally
modified version of ENTRY is used, the instructions in this chapter may also require
modification.
Refer to chapters 3 and 4 for a description of forms design and to chapter 6 for a
description of the intrinsics associated with ENTRY.
Protected and Unprotected Fields
Each form contains protected fields that you cannot change, and unprotected fields where
you key in data. Protected fields can consist of field titles, report headings, or
display
only
fields to which the system sends data. Data entered at a keyboard can only be keyed
into unprotected fields.
Error Detection
If ENTRY detects an error after you enter data, ENTRY highlights the field(s) in error and
displays an error message. You can then correct the error and reenter the data on the form.
Data Modification
After data has been entered, you can review it and modify it if desired. The entered data
can be reviewed in a different order than it was entered.
