Hans is correct it was V1R3.  Now the real question.  What is the difference
between a READE with or without factor 1 specified.  My understanding is
there are certain circumstances when using an update file with factor 1
specified for a READE where RPG can not turn on the not found indicator if
the next record (i.e. the one which has a key not equal to factor 1) is
locked by another user.  This never happens when factor 1 is not specified.
