Designing and Using Forms
INTRODUCTION
5
Using the terminal's function keys, you can create a data entry form on the screen to simulate
a ready-made form on the line printer, or to structure data sent to a data base. After the data
entry form is created, you can read it into computer memory, using a program designed for
the purpose, and incorporate it into a computer program. Then, you can use this program to
print out the data entry form on the terminal screen for easy data entry.
To expedite data entry into the form, you can initiate Format mode, in which you can tab
from one field in which data is to be entered to the next. When the form contains all the
desired data, you can press the. key to send the entered data to the computer.
The data entry form can contain four types of fields: ((unprotected", ((protected", Utransmit-
only" and «security" fields. Data can be entered in unprotected and transmit-only fields and
sent to the computer using the. key; data in protected fields stays fixed on the screen-and
cannot be modified; data entered into a security field is not displayed, when it is typed in. By
using the line drawing set and display enhancements to create your form, you can highlight
these fields for the operator. Figure 5-1 illustrates a form with protected and unprotected
fields.
