Steve,

Will not work, since Bill does not have a master-detail window, he is
only looking at the detail side and are basically looking at not
showing "orphaned" detail records in the view.

Your head model is incorrect<g>
Each DBServer has it's own defined workarea (held internally), look at the
SDK code for DBserver{} that's why you NEVER have to select( aWorkArea )
before using a dbserver.

I've never used 2.8, so my question
- is DBSetRestoreWorkArea() a method of the server or a compatability
function for people who mix Clipper & VO syntax??

To me your problem is using SELF and/or objects in codeblocks, that really
is a programming error IMO.
Eg
> self:oEntryDS:setFilter({ |ogHold| ogHold:seek( _FIELD->entrynum,
> rue ) }
should be
x := SELF:ogHold
self:oEntryDS:setFilter({ || x:seek( _FIELD->entrynum, true ) }

> self:oEntryDS:setSelectiveRelation( self:oKeyWordDS, "entrynum" )
Have you tried
self:oEntryDS:setSelectiveRelation( self:oKeyWordDS,
'_FIELD->entrynum' )

Have you moved on to another problem??
I thought from your previous posts you were referencing the ogHold server??

I believe he's trying to show details in a browser on a SubDataWindow (at
least thats what I gather from his naming syntax), if so then IMO a
relationship is a better option than using a filter.
