Comments
If a user wants to add a word to the system word list, which is available
whenever the system dictionary is enabled (see EnableSystemDictionaryHRC), then hwl should be set to the predefined constant HWL_SYSTEM. Words that are not
normally found in a dictionary, such as a person's name, can be added to the system
word list. How this list is implemented, its size, or if it even exists,
depends on the recognizer. A typical recognizer might maintain a thousand-word list,
replacing random entries on overflow.
The HWL_SYSTEM constant cannot be used in any of the other word-list
functions. For example, it is not possible to destroy the system word list with the DestroyHWL function.
For a description of word lists and how a recognizer uses them, see
"Configuring the HRC" in Chapter 5, "The Recognition Process."
