TAILORING AN APPLICATION

Providing a Compressed Format

When you supply a value for the INCLUDE attribute, consider the

following:

• If you do not include all the field names in a record

description, the application does not display the omitted

fields.

• If you use the application to update a record and one or more

fields do not appear on the screen, the application uses the

original values of the fields for the updated record.

• If you use the application to insert a record and one or more

fields do not appear on the screen, the application uses a

default value for these fields. The application uses zeros

for numeric fields and blanks for alphanumeric or alphabetic

fields.

Providing a Compressed Format

If several fields appear in a box, you might want to provide a

compressed format for that box. A compressed format often

improves the appearance of the screen. Consider, for example,

the "employee-info" application. You could improve the

appearance of the screen displayed by this application by

supplying a compressed format for "employ-box." To provide this

format, you could include the following in the series of commands

used to describe "employ-box":

SET SCREENFORMAT COMPRESSED

Figure 6-6 shows the screen that "employee-info" will

display if you supply the attribute values discussed thus far.

This figure also shows the preceding SET SCREENFORMAT command in

the series of commands used to generate the application.
