>Hi, I was flustered in attempting to have a listbox scroll down thru some records(ccpay98.dbf) and have an adjacent editbox display the matching records from another dbf, linked, of course, on a common field.
>Using "THISFORM.MYEDITBOX2.VALUE=STR(CCPAY98.TOT_COST)" works only to display the dbf the listbox is using.

When you scroll down, you didn't change Listbox.Value yet. It will happen only if you click on another item, then Listbox.Value will change and you can fire Thisform.Editbox.Value=... from Listbox.InteractiveChange event.
