Curt,
If you mean with a worksheet function, then No. This can only return a
value. e.g.

Public Function InvalidWorksheetFunction(argValue As Variant) As Long
Debug.Print Application.Caller.Offset(0, -1).Address
Application.Caller.Offset(0, -1).Value = argValue
InValidWorksheetFunction = 1
End Function

However, called from VBA, this is valid
Public Function ValidFunction(argBase As Range, NewValue As Variant,
Optional ColOffset As Long = -1) As Boolean
argBase.Offset(0, ColOffset).Value = NewValue
ValidFunction = True
End Function
although you should add checking of a valid Offset, so you are not off the
sheet.

locations
and return data to location in precedding column.
