Trace output options
0 | A: prints the states of the scanner automaton

2 | G: prints the syntax graph of the productions
3 | I: traces the computation of the First sets
4 | J: prints the sets associated with ANYs and synchronisation sets
6 | S: prints the symbol table (terminals, nonterminals, pragmas)
7 | X: prints a cross reference list of all syntax symbols
8 | P: prints statistics about the Coco run
Trace output can be switched on by the pragma
