Dictionary/TurboImage anomaly

[Deskin, Bob]

Check the RECORD definition for FS-REC-YEAR-A. Is there an OPEN option? As I
recall, you do need some reference to the actual dataset name to access it
but that can be done using the OPEN option.

On the other hand, if all you're doing is accessing the detail dataset and
not the master or auto master, then we don't physically access the master.
We would do a DBFIND (I think, it's been a long, long time since I coded
IMAGE intrinsics) to establish the chain. The dataset reference is to the
detail even though you're really looking at the master. You also specify the
search item (index) which is how IMAGE establishes the master to look at. So
if that's what you're doing, PowerHouse wouldn't need the actual master
dataset name.

Here is the index information for a detail dataset:

-- Index Contents --

 ** FS-REC-YEAR is a 4 byte   REPEATING ALTERNATE  index **
 ** that links to FS-REC-YEAR-A **


    Segment                              Type            Size  Ord  Offset
    FS-REC-YEAR                          CHARACTER          4    A       0

The dataset FS-REC-YEAR-A does exist in the PDL source file, of course, but
the dataset does not exist in the data base itself. In the data base, the
dataset where the chain head is for FS-REC-YEAR is called FS-RECORD-YEAR.

Yes, everything seems to work properly. I ran QUIZ with a CHOOSE
FS-REC-YEAR PARM and was able report the records that exist.

I imagine that the only time PowerHouse cares about these links is in
creating a data base from the dictionary. In field conditions <grin> the
PowerHouse products rely on DBINFO to resolve such issues.

Is that correct?
