GRAMPROG is a 'fake' token that is actual passed as an arg to yyparse() to say what type of thing we want to parse; i.e. its an extension to the usual yacc/bison stuff which just has a hard-coded start, e.g. 
%start prog

[download]
or similar.

So the GRAM* stuff is fake; the rest of the tokens are returned by llyex in toke.c in the usual way.
