# LIST OF RESERVED WORDS

The following is a list of "reserved" words used by mom. Before changing the name of any macro or document element tag with ALIAS, I strongly recommend doing a search of this page for your proposed new name. If you find it in the left hand column, DON'T USE IT. Choose something else instead.

Anyone interested in playing around inside mom's macro file (om.tmac) will find this list useful as well since it lists all (I hope) the macros, strings, diversions and number registers mom uses, along with brief descriptions of their functions.
