The IEBISAM program is no longer distributed. Starting in z/OS V1R7, ISAM data sets can no longer be processed (created, opened, copied or dumped). ISAM data sets that are still in use must be converted to VSAM key-sequenced data sets.

Prior to z/OS V1R7, you could use access method services to allocate a VSAM key-sequenced data set and copy an ISAM data set into it. Access method services are also used to manipulate VSAM key-sequenced data sets. See z/OS DFSMS Using Data Sets and the REPRO command in z/OS DFSMS Access Method Services Commands for information on converting ISAM data sets to VSAM key-sequenced data sets.
