| Release 3.6 | This release incorporates a fix to handle base records that are shorter than the AIX key, and a minor change to make it easier to identify the release. |
| VSE Versions of the KWIKLOD program are now provided that do not rewind the input tapes at the end of processing. | |
| Release 3.5 | NOCI no longer has to be specified when processing compressed datasets if the dataset was defined as compressed when defined with DEFINE CLUSTER. KWIK-KEY will automatically perform VSAM record I/O when it detects the compressed attribute for a VSAM dataset. |
| Support for VSAM System Managed Buffers (SMB). All VSAM control blocks and buffers are now above the 16 meg line. | |
| Versions of the KWIKLOD program are now provided that do not rewind the input tapes at the end of processing. | |
| Release 3.4 | The MVS programs now operate in 31-bit mode. The previous requirement that all VSAM buffers be below the 16mb line is removed. |
| XXL support (for very large VSAM files) under VSE has been added. | |
| Release 3.3 | AMAXLEN installation option removed. Maximum alternate index record length computed and acquired dynamically at execution time. |
| Release 3.2 | Withdrawn. |
| Release 3.1 | Withdrawn. |
| Release 3.0 | Release of VSE KWIK-LOAD. VSE users will now be able to load the VSAM base cluster and build an alternate index at the same time. |
| Ability to build multiple alternate index datasets with one pass of the base cluster. KWIK-KEY will build up to nine (9) alternate index or cross reference datasets while reading the base cluster records only once. KWIK-LOAD will also build up to nine (9) alternate index or cross reference datasets while loading the VSAM base cluster. | |
| Ability to limit the number of base cluster records associated with one alternate key. The new MAXDUP parameter allows users to eliminate excess base cluster keys for an alternate key. | |
| Performance optimization suggestions. A new section has been added to the reference manual with suggestions to improve the performance of KWIK-KEY and KWIK-LOAD by fine tuning sort features and VSAM dataset options. | |
| Improved documentation. Separate sections for MVS and VSE control statement formats. | |
