Updating a record using Embedded File IO processing


I am wanting to update a record using SQL.   I already have the record locked and have "Set" the necessary fields to a new value.  I wish to update the changed fields but I do not want to build the update to list the set of fields only to later need to update another set of fields.

Like this old way.

KeyL        Chain        FileA
        Eval        Field1 = 'ABC'
        Eval       Field3 = '123'
        Update FileA

Later I may have:

KeyL        Chain        FileA
        Eval        Field9 = 'ABC'
        Eval       Field10 = '123'
        Update FileA

Is there a way to do this with SQL or do I have to create an update statement for all field combinations that may be updated.

Thanks
