Yacc Question

[Jay Weber]

When an error is detected, the yacc variable "yychar" will be set
to the lookahead token number.  For character tokens like ';', the
token number will be the integer value corresponding to it, but
if it is a declared token then you will have to come up with a
cross-reference table if you want what the token is in english.
