IEBUPDTE can be used to create a library of partitioned members, if those members have logical record lengths of 80 or less. In addition, members can be added directly to an existing library, provided that the original space allocations are sufficient to incorporate the new members. In this manner, a cataloged procedure can be placed in a procedure library, or a set of job or utility control statements can be placed as a member in a partitioned library. These libraries may be either partitioned data sets or PDSEs.
