Well, no, the error messages just state "expected this, found that",
without actually giving a REAL hint...

The declaration would be something like this

Type tStateRecord = Record
                                         StateAbbrev : String [4];
                                         StateName   : String [40];
                                         InLower48    : Boolean;  
                                    end;
        tStateArray = Array [1..MaxNoStates] of tStateRecord;

Var {or Const, so it's initialized only once}
        States : tStateArray = (  (StateAbbrev  : 'AL', StateName :
'Alabama', InLower48:TRUE),
                                                 (StateAbbrev  : 'AK',
StateName : 'Alaska',     InLower48:FALSE),
                                                 ...
                                               );

Various versions of parenthesis just vary the error message, either the
above mentioned "expected this, found that" or "filed xyz not initialize"...
