gnubol: Record delimiter clause and parse order

[Matthew Vanecek <linuxguy@directlink.net>]

Tim,
got a couple of questions.  The specs I have list RECORD DELIMITER as
required for sequential file i/o.  Now, I've never used that clause in a
program before, so input is welcome--with lack of other input, I'm gonna
make it optional.

Also, for writing the parser, I'm a little vague as to how to make order
not matter.  If I do something like:

select_clause_opt:
/* nothing */
| SELECT opt_optional_clause file_desc_name
assign_clause
opt_access_mode_clause
opt_file_status_clause
opt_lock_mode_clause
opt_organization_clause
opt_padding_char_clause
opt_record_delim_clause
opt_reserve_area_clause
opt_sharing_clause
;

then it will expect to find the clauses in that order, when, of course,
the order doesn't really matter.  I'm not expert enough w/yacc to know
the workaround, so a hint would be very welcome (e.g., "look at
this-n-such section of code" or whatever).

ciao,
