GOAL:
How is _field joined to _file?
FIX:
The OF operator is handled in a special way with few metaschema tables such as _field and _file. For instance, Progress automatically translates the following 4GL:
FIND _file OF _field
into:
FIND _file WHERE RECID(_file) = _field._File-recid.
Therefore, if you need to achieve the join explicitly, then you should use the above code.
