Thanks for getting back.

The command is like this.

SCAN FOR transact.idate<=m.updtdate AND ;
transact.itrancode="Q" AND ;
transact.ilookfordd="Y"

...

ENDSCAN

The table has (among others)indexes on idate and itrancode.
I've never heard of set collate before, (There's nothing in my manual)
but set ("collate") yields "machine". I don't know how to find the collate setting of the index. Is this a 2.6 thing?
