Parser failing on codebook

[Anonymous]

I'm trying to parse my first codebook, which I've had to manually extract from a PDF.  I took the raw codebook text and ran it through a couple of sed scripts to produce what looks to me like a valid codebook.

Running that codebook through the parser throws a parse exception on the first field.  The stack trace is:

class net.sf.cb2xml.sablecc.node.TDataName, state : 0, text :
java.lang.RuntimeException: fatal parse error

FIELD-MAST
=== buffer dump end ===

… 3 more

The codebook is several pages long, but the start of it is:
01    FIELD-MAST.
02    OIL-CODES.
03    TYPE-REC PIC 9.
03    DIST PIC XXX.
03    FIELD PIC 9(8).
03    OPR PIC 9(6).
03    LEASE PIC 9(5).
03    LSE-FILLER PIC 99.
03    OFFSHORE PIC 9.
02    FIELD-DATA.
03    F-NAME PIC X(32).
03    COUNTY PIC 9(18).
03    COUNTIES REDEFINES COUNTY OCCURS 6 TIMES PIC 9(3).
03    DISC-DATE PIC 9(8).
03    D-DATE REDEFINES DISC-DATE.

I'd appreciate any help understanding what's going on.

thanks,
