Hello Nick,
Am I that blind? :-) I was always looking out for some "second key" set to *HIVAL to tell SETGT what to do.
Wait. If you need to read from a *Specific* point inside the key, you have to use 2 keys, one for setgt and one for the readp (or a single key specifiying number of filed to use). If you just need to read all record that have that key, just use a single one.

A 'classic' example with orders row:

Setgt (OrdNum) OrdRow
Readpe (OrdNum) OrdRow

will read all order's row for the given order, while:

Setgt (OrdNum:100) OrdRow
Readpe (OrdNum) OrdRow

will read from highest row less or equal 100, and then down to lower one.

So, you don't need *Hival/*Last if all you want is to read the whole 'keyaed' row.
