For the IIPS student and author IDs, the IBM-supplied default is an S (for student) or an A (for author) followed by the TSO/E user ID. This default appears in fields prompting you for an IIPS student or author number. To use this default, keep the IIPS = USERID field on the defaults panel set to Y. If you set IIPS = USERID to N, fields prompting you for a student or author number will contain an S or an A followed by blanks.
