>>Is there a quick way to replace all the fields in a record that have a .Null. value to a blank value of the field's type, i.e. " " for char, 0 for numbr, .F. for logical, etc.? If it is easier to do this in an array, please let me know.

Jim only wanted to do this for a record, not for all fields in a table.
If it's not broken, fix it until it is.
