# 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.

                               it should be deferred, when, in fact,
                               it's an overflow; this register lets

    +++ALIASES+++

    Please note:

    Prior to version 1.1.9, all macros that included the word COLOR had
    aliases that used COLOUR instead.  This convenience has now been
    removed, in an effort to reduce the size of the om.tmac file.

    Furthermore, if you want the convenience, you'll have to edit the
    om.tmac file.  Simply aliasing, say, HEAD_COLOR as HEAD_COLOUR will
    not work, owing to significant changes in the handling of
    docelement control macros that end in _COLOR.
