LEX/YACC - grammar problems and printing error messages

I have been developing a data conversion program using lex and yacc in
order to generate a text file to import into a new database. (I know AWK
could be used, but I want to adapt this conversion process for an
interactive mode.) As grammar errors are found, I was wondering how to
associate the source line/column with an appropriate error message. Since
lex deals with tokens and yacc parses the grammar, how can I get the
current line of input to print error messages? Actually, the data is
organized as a multi-line record and I will write the entire record to an
error file and then use a comment line to display the error.

[Bison has some extra hackery to associate a line and column number with
every token, though it still won't give you the whole line. See the next
message for some suggestions. -John]
