add records & use of @wlf

[Dennis Malen]

Simple question.

Can I use "@wlf" when sitting in a screen in "add records".

I want the operator to put in a client code which is a string of numbers.
When leaving that field I want the system to look up in the data base the
name of the client (and display it on the screen) in order to verify that
the correct client code was entered. The result of the lookup would be
populated in a dummy field.

It does not work for me.
