incontrovertible

Good progress this morning.  tok.c, help.c are done.  tok.c is weird since it contains yylex (i.e. lex), which seems particularly strange since I don't recall Larn parsing anything more than 3 characters at a time for spells.  It's only called by main though, so I may be able to just remove it later.

And then I get to drawscreen().  Yay!  Time to start rendering!  drawscreen lives in display.c, and the first thing I see is this:

#define botsub( _idx, _x, _y, _str ) \

 if ( c[(_idx)] != cbak[(_idx)] ) \
 { \
 cbak[(_idx)] = c[(_idx)]; \
 cursor( (_x), (_y) ); \
 lprintf( (_str), (long)c[(_idx)] ); \
 }

Incontrovertible.  I mean, I could always just redefine the character class to be all the fields in a union with an int array.  But really, that's terrible.  I don't currently understand how many places this is used, but I'm hoping it's 0 or 1 because this is just terrible.
