TAILORING AN APPLICATION

Reordering Screen Fields

When you supply DDLHEADINGS as a value for the HEADINGS

attribute, the application uses the field name as a label for any

field in a record description that does not have a HEADING

clause.

Reordering Screen Fields

If you want to define the order in which fields appear on the

screen, you must supply a value for the INCLUDE attribute.

Consider, for example, the "employee-info" application. To

provide an attractive and useful screen for this application, you

should reorder the fields for "employ-box" so that:

• The join field ("empnum") appears after all the other fields

in the box

• A key field (such as "empname") appears as the first field on

the screen

• Fields (such as "age" and "salary") that contain sensitive

information do not appear on the screen

You can reorder the fields in "employ-box" by including the

following in the series of commands that describe this box:

SET INCLUDE (empname, dept, job, vacation, empnum)

Figure 6-5 shows the screen that "employee-info" will

display if you supply the attribute values discussed thus far.

This figure also shows the preceding SET INCLUDE command in the

series of commands used to generate the application.
