Re: Virtual SHARE Ageenda
In TSS/360, VPAM datasets can have both sequential and index sequential members; you can read and write withing a member either sequentially or by key, including inserting a new record between existing members. VIPAM is a colloquial term for a VPAM dataset containing VIS members. From the documentation: Three special Data Management Access methods -- the virtual Access Methods (VAM)-- have been provided with TSS. They are specifically designed for a time-sharing environment and are used to read and write data to and from direct access storage devices. For all three of the VAM access methods, the data set management (for example, formatting) is performed in virtual storage -- using virtual addresses that are part of the user's virtual storage address space -- although physical device management (e.g., I/O) is performed by system programs in resident storage. Each access method provides access and processing capabilities for data sets organized in a specific manner. * sequentially (Virtual Sequential Access Method -- VSAM) * indexed sequential (Virtual Indexed Sequential Access Method -- VISAM) * partitioned (Virtual Partitioned Access Method -- VPAM) In TSS, data sets organized for processing by one of the virtual access Methods are generally referred to as VAM data sets. and Partitioned Organization A data set with partitioned organization has elements, or members, that are other data sets; these elements are in either sequential or indexed organization. -- Shmuel (Seymour J.)

Re: Virtual SHARE Ageenda
Re FBA, they did it for other systems, and TSS/360 used page formatted volumes for everything except compatibility volumes, so from a technical perspective it's a no brainer, although direct use of SCSI DASD might make more sense these days. Politically, it's a thorny issue. I'd love to see them extend VSAM to the level of TSS while they're at it, e.g., VIPAM. -- Shmuel (Seymour J.)

There will obviously be no travel expenses if you have access to high enough speed Internet. There are opportunities for Birds Of a Feather sessions. If I sign up, I might try to set up a BOF session on COBOL 2014, some of the very useful features and whether they are 20 - 40 years too late because organizations have already implemented work-arounds and won't revisit the code? I also am interested in discussing whether making the effort to have z/OS handle FBA devices for FBA data sets (all VSAM, PDSEs, page data sets, etc.) would be worthwhile and creating FBA equivalents of SYS1.NUCLEUS (combine it with the IPL text?)
