Local identifiers that possibly are set and referenced once (REDU5)
This is a list of all local identifiers that possibly are set and referenced just once. They are referenced in unknown fashion, and the parser cannot determine whether they are set or just referenced in these locations. It may be more efficient to skip this intermediate identifier.
Identifiers that are first set as a var parameter in a call to a subprogram, and afterwards referenced, are not reported. Also, when the identifier is referenced in a loop, it is not reported.
