Normal words are associated with internal bit patterns consisting only of 1s. Normal words can have one or more 1 bits associated with them. The example below is for the simplest and most common case, where a single bit is associated with a word. When such a word is combined with a label containing no words, the resulting label contains just the word.
Word1 | 1------- |
(NULL) | -------- |
Word1 | 1------- |
In the following example, two normal words each associated with different 1 bits are combined. The resulting label contains both words.
Word1 | 1------- |
Word3 | --1----- |
Word1 Word3 | 1-1----- |
