/*
** How to use the TAGMAP macro
**
** You  have  a structure named "NewWindow".  In this structure you have an
** entry named "LeftEdge" containing a 16 bit integer.  Now, you have a tag
** named  "WA_Left"  that  should  be maped into "LeftEdge".  If the tag is
** missing the value "0" should be store in "LeftEdge.  To do this you must
** create a TAGMAP item like this:
**
** TAGMAP(WA_Left,NewWindow,LeftEdge,0,        REAL,  WORD,DEFAULT,   0)
**        ^       ^         ^        ^         ^      ^    ^          ^
**        ID      Structure Offset   MissFlag  Number Size Default is 0
**
** If  "LeftEdge"  is  the  position  of  the  left  edge of a window to be
** created,  it  may  be a better idea to center the window if no "WA_Left"
** tag  is found.  However to center a window you need to know the width of
** it  and  the  screen it will be created on.  So, if the "WA_Left" tag is
** missing  we  must know this.  The following TAGMAP item set bit 0 of the
** missflags.
**
** TAGMAP(WA_Left,NewWindow,LeftEdge,1,        REAL,  WORD,NODEFAULT, 0)
**        ^       ^         ^        ^         ^      ^    ^          ^
**        ID      Structure Offset   MissFlag  Number Size No default Ignored
