/****************************************************************************
**
*F Match( <symbol>, <msg>, <skipto> ) . match current symbol and fetch next
**
** 'Match' is the main interface between the scanner and the parser. It
** performs the four most common actions in the scanner with just one call.
** First it checks that the current symbol stored in the variable 'Symbol'
** is the expected symbol as passed in the argument <symbol>. If it is,
** 'Match' reads the next symbol from input and returns. Otherwise 'Match'
** first prints the current input line followed by the syntax error message:
** '^ syntax error, <msg> expected' with '^' pointing to the current symbol.
** It then skips symbols up to one in the resynchronisation set <skipto>.
** Actually 'Match' calls 'SyntaxError' so its comments apply here too.
**
** One kind of typical 'Match' call has the form
**
** 'Match( Symbol, "", 0L );'.
**
** This is used if the parser knows that the current symbol is correct, for
** example in 'ReadReturn' the first symbol must be 'S_RETURN', otherwise
** 'ReadReturn' would not have been called. Called this way 'Match' will of
** course never raise a syntax error, therefore <msg> and <skipto> are of no
** concern. The effect of this call is merely to read the next symbol from
** input.
**
** Another typical 'Match' call is in 'ReadIf' after we read the if symbol
** and the condition following, and now expect to see the 'then' symbol:
**
** Match( S_THEN, "then", STATBEGIN|S_ELIF|S_ELSE|S_FI|follow );
**
** If the current symbol is 'S_THEN' it is matched and the next symbol is
** read. Otherwise 'Match' prints the current line followed by the error
** message: '^ syntax error, then expected'. Then 'Match' skips all symbols
** until finding either a symbol that can begin a statment, an 'elif' or
** 'else' or 'fi' symbol, or a symbol that is contained in the set <follow>
** which is passed to 'ReadIf' and contains all symbols allowing one of the
** calling functions to resynchronize, for example 'S_OD' if 'ReadIf' has
** been called from 'ReadFor'. <follow> always contain 'S_EOF', which 'Read'
** uses to resynchronise.
**
** If 'Match' needs to read a new line from '*stdin*' or '*errin*' to get
** the next symbol it prints the string pointed to by 'Prompt'.
