2) Unless it has changed in a recent release, the parentheses on the chain is reserved for a compound key, so they should be removed.


The list-of-keyfields has always supported having just one key.

If the search key has exactly the same type and length as the real key, it could be coded with or without parentheses. But if you need type/length conversion, or you want to code an expression, then you would code the parentheses.

I would always code the parentheses for keys, to visually distinguish between relative-record-number chains.
