77 | ||
78 | This is a macro so that the parser can use the fancy syntax. The name | |

2b7ce7a5 MW |
80 | string. Then the PARSER is invoked and three values are returned: the |
81 | result of the parse, or `nil' if the main parse failed; a list containing | |
82 | the number of errors and warnings (respectively) reported during the | |
83 | parse; and a list consisting of the lookahead token type and value, and a | |
84 | string containing the untokenized remaining input. | |
85 | ||
86 | If BACKTRACE is nil (the default) then leave errors to the calling | |
87 | environment to sort out (e.g., by entering the Lisp debugger); otherwise, | |
88 | catch and report them as they happen so that you can test error recovery | |
