Exception in thread "main" java.lang.Error: Error: could not match input
at grammar.Yylex.yy_scanError(Yylex.java:442)

where its declared as ...
STRCST                  = \"(%[a-z])(%.)*\"|\" \"

Also tried matching it directly ...
      "\" \""                  { return token(sym.STRINGCONST); }

it matches the other string constants i need like "%n" etc
