Figure 2-3. Attribute Table With an Override Box-Attribute Value

After you enter the ADD BOX command, ENABLE examines the contents

of the attribute table to obtain the description of the box. If

certain attributes retain a null starting value (you have not

supplied a current or override value), ENABLE supplies a default

value. For example, the starting value of the DATAFILE attribute

in Figure 2-3 is null and the attribute table contains neither an

override nor current value for this attribute. Since this

attribute has a default value, ENABLE will supply "employee" as

the default value of the DATAFILE attribute for "employ-box."

Figure 2-4 illustrates the partial contents of the attribute

table when ENABLE adds the default value of the DATAFILE

attribute. ENABLE obtains this default value from the record

description in the dictionary.
