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.
