I am not sure of what it is you are doing. Can the Account Number field
in the SFL field be entered or altered by a user? If so, is there a
requirement to be sure the newly entered number is ( or is not) a
recognized and existing Account Number?
If it is as I am guessing it to be, it would seem the easier solution is
to create a data structure element of the subfile fields and then make
the an array of the subfile. That has a lot of benefits once you do the
initial set up. One benefit is the ability to sort the subfile
ascending or descending, by any column in the subfile. Another benefit
is the Undo function becomes easy to implement.
To your point though, when the user keys the Enter key it can make the
entire edit processing much easier.

I have a subfile that is used for data entry. One of the columns in the subfile is an account number. An account number can only appear in the subfile once (i.e. Unique key). Does anyone know how to check for that, other than writing the subfile to a temporary uniquely keyed disk file, and monitoring for a duplicate key error?
Thank you,
Doug
