Aloha from Hawaii,

My question is probably simple it's just that I can't figure it out:

I have a table that has an index on a job shift number and worker code.
I want to seek a record based on the job shift number and worker code.
What command do I use to seek for this record?
I think I'll use the SEEK command but how is the syntax for this multiple field search?

Lost in Hawaii,
Mike
