Re: Reading/Chaining into a DS, and RNF0202

Now, if let's say that I have a file, that is JUST like the FAMLY file
in the example, with the same field names and all (Let's call it
DFAMLY), except for _one_ extra field in the beginning of the record
format.  I need to read a record from the FAMLY file, CHAIN to find
the matching record in the DFAMLY file, and compare the fields (except
the extra one).

To accomplish this, I wanted to create a data structure that matched
the record format of each file, one for FAMLY, and one for DFAMLY. 
Then, I wanted to make a third DS, that matched the record format of
the FAMLY file, but base it on a pointer to the DS for the DFAMLY
file.  I assumed it would match the fields by name, as per a book I
have read.

Instead, when I read a record from the DFAMLY file into the data
structure for the DFAMLY file, I check the values in the based data
structure, and the fields are offset in the subfields, by three bytes
(the size of the 'extra' field).

Any help would be greatly appreciated.
