/*
 * scan.h - the jam yacc scanner
 *
 * External functions:
 *
 *	yyerror( char *s ) - print a parsing error message
 *	yyfparse( char *s ) - scan include file s
 *	yylex() - parse the next token, returning its type
 *	yymode() - adjust lexicon of scanner
 *	yyparse() - declaration for yacc parser
 *	yyanyerrors() - indicate if any parsing errors occured
 *
 * The yymode() function is for the parser to adjust the lexicon of the
 * scanner.  Aside from normal keyword scanning, there is a mode to
 * handle action strings (look only for the closing }) and a mode to 
 * ignore most keywords when looking for a punctuation keyword.  This 
 * allows non-punctuation keywords to be used in lists without quoting.
 *
